Genome Mate: ICW, Triangulation and Overlapping Segments

The purpose of the blog is to describe ICW, Triangulation and Overlapping Segments from the profile perspective in Genome Mate as that is how the data is presented in the application.

One of the most frequently asked questions is what is the difference between In Common With (ICW), triangulation and overlapping segments.  Let's start with a definition of each in relation to the Genome Mate profile person before moving on to more details.

  • In Common With (ICW) - ICW simply means that two Relatives have some DNA in common and are thereby related to each other but not necessarily on the same segment as the profile person.
  • TriangulationTriangulation means that the profile person plus two or more people are related to each other on the same DNA segment and thereby share a common ancestor. 
  • Overlapping Segments - Overlapping segments are DNA segments from two or more Relatives whose start and end points overlap each other.

Loading data in Genome Mate is complicated due to the need to accommodate different data sources and formats.


Getting Started Guides

Here are the links to some of the Getting Started guides.  The focus of this blog will be limited to just ICW, Triangulation and Overlapping Segments.

In Common With (ICW) in Genome Mate


In Genome Mate, there is an ICW indicator next to the Relative's name and if you hover your mouse over it, it will highlight the other relatives on that segment who are related to that person.  However, it says nothing about if they are all related on that particular segment.

When a segment crosses a centromere, there is a greater chance the segment is a mismatch or IBS (identical by sequence) rather than IBD (identical by descent).  When this occurs, the ICW group on the graph will be an orange color to alert to the possibility.

The ICW group can be set to any value by clicking on a DNA segment and setting the value in the Match details page.  However, note that, if known, it should start with M for maternal or P for paternal for surname matching and chromosome mapping to work correctly.

Keyboard shortcut:  If you left click on the ICW indicator, you can mark every person highlighted with a value you enter except for those who have an * in their ICW.  If you right click on the ICW icon, it will copy the ICW group value contained in that Relative record to all highlighted relatives except for those who have an * in their ICW value.  Use this with caution since ICW relatives are not always related to each other on the highlighted segment.

There are several ways to load ICW data depending on the data source but note that Relative data must have been loaded first or the ICW data will be rejected.

  • 23andMe - The recommended method of loading ICW for 23andMe is to use the 529andYou CSV file but there are other, more time consuming and less comprehensive ways to get the data.  In order of preference:
  • On 23andMe > My Results > Ancestry Tools > Countries of Ancestry > Select Relative name > Click Download {Relative's Name}'s Countries of Ancestry Matches (CSV)
  • In Genome Mate > Select one of the Relative's DNA Segments > Add ICW >  Import Data from CSV File >Select file named ancestry_finder_{name}{date}.csv 

  • FTDNA - The only way to import ICW data for FTDNA is to use DNAGedcom.
  • On DNAGedcom > Family Tree DNA >  Download Family Tree DNA Data > Enter Kit # > Enter Password > Get Data > Wait for processing to finish > Find zipped file in your download folder and extract files 
  • In Genome Mate > Import Data > Select Data Source > Load ICW CSV file from DNAGedcom > Import Data from CSV File > Select file named {kit}_ICW.csv

  • GedMatch -  ICW is loaded when loading the segments from Segment Triangulation (see blog) but it is limited to the top 200 matches.  
More ICW data can be loaded one relative at a time by:
  • On GedMatch > 'One-to-many' matches > Enter kit number > Display Matches > Select data (Ctrl or Cmd a) > Copy data (Ctrl or Cmd c)
  • In Genome Mate > Select one of the Relative's DNA Segments > Add ICW >  Copy Data (Ctrl or Cmd v) > Format
ICW data provides clues that the researcher can use to dig further into family trees to see if there is a connection between Relatives on the DNA segment in question.  Not having an ICW between two relatives is a good way to avoid researching people not related.


Triangulation

Triangulation means that the profile person plus two or more people are related to each other on the same DNA segment and thereby share a common ancestor.  This is determined by a three way match between the profile person and two relatives (P = A, P = B, A = B).

Automation of triangulation is only available for 23andMe data imported from the 529andYou CSV file and the Segment Triangulation data from GedMatch (limited to first 200 top Relatives).  

If triangulation data has been loaded into Genome Mate then clicking on a Relative's DNA segment will show the triangulated data in the upper middle box of the match details page. 

Triangulated relatives establish an ancestral line on which they all share a common ancestor even if that ancestor is not currently known.

Overlapping Segments

Overlapping segments are DNA segments from two or more Relatives whose start and end points overlap each other.  Each overlapping segment contains DNA from both the paternal and the maternal sides of the family so segments that overlap are not necessarily related to each other.  

Use DNA matches to known family members to set the segment's ICW group to either P (paternal) or M (maternal).  Otherwise, any ICW value is okay to indicate a group of triangulated matches.

Segments that have been identified as maternal or paternal but whose overlap is small may not be related.  To to filter those out, a default overlap value can be set and compared to the segment's start and end points to determine if it should be displayed.  To set the default value:

  • In Genome Mate > Options > Set Minimum Segment Overlap

There are tools in Genome Mate to work with overlapping segments:  

  • On Genome Mate graph:  Left click on the circle icon next to the profile name and all of the segment overlaps for that particular segment will be displayed.  If the segment has been identified as maternal or paternal, it will display the corresponding maternal or paternal segments plus those that have not been identified.  This display ignores the default overlap value and shows all overlaps. Use ESC to return to a full display.
  • On Genome Mate graph:  Right click on the circle icon next to the profile name and an Overlapping Segment Page will be opened showing all of the DNA segments for all sources (23andMe, FTDNA, etc.) that overlap the selected segment by the default overlap value.  It shows the common surnames shared among those listed on the page. Clicking on a Relative in this list will open their Match details page.
  • On Match Detail page:  In the lower right corner is a list of segments overlapping the selected DNA segment by the default value along with shared surnames.
Overlapping Segment Page

The Overlapping Segment Page is my primary work space when trying to identify common ancestors as it gives a global view of the segment in question.

Getting Started with Genome Mate using 23andMe Data

Genome Mate is a desktop tool used to organize in one place the data collected while researching DNA comparisons.  Besides data storage it has many features to aid in identifying common ancestors.  It can be downloaded at http://genomemate.org/



The following guide was originally put together by George Cunningham and published with his permission.  It has been edited to reflect changes in the application.


23andMe Getting Started Guide

There are three steps required to load 23andMe data:  Setting up a profile, load DNA segments and loading associated Relative data.  Under step 2, loading DNA segments, there are multiple options for obtaining that data.  Please read each carefully before proceeding.

Step 1:  Create a Profile


  • First create a profile in Genome Mate for each kit that you manage
    • Profiles > Add new profile
  • Put in a name, any name will do, but
    • You are a good choice for the profile person.  
    • If your going to use data from 23andMe for the profile person, the profile name MUST match the 23andMe name.
  • Load a gedcom file for each profile if you have one.  If not just continue.
    • The gedcom file can be all of your relatives and more
    • Genome Mate will ask you for the name to associate with the profile person, and will strip out all but the profile person's direct ancestors.
    • The gedcom file format must be 5.5 in UTF8 format


Step 2:  Load 23andMe DNA Segments


Import Data Page

There are several methods for loading the DNA segment data for 23andMe profiles that can be mixed as needed.
529andYou:  The recommended method of importing 23andMe segment data is to use Neanderling's Chrome Plugin, 529andYou as it not only provides DNA segment data but triangulation and in common with (ICW) information as well. The Chrome browser is required.
  • Get Chrome Browser here
  • Get 529andYou here and be sure to click yes when asked to create a Chrome database.
  • Read about 529andYou here 
  • On 23andMe > My Results > Ancestry Tools > Family Inheritance: Advanced > Select any Compare profile > Compare > View in a Table > Click on 529 icon in upper right corner to open new tab 
  • On the 529andYou tab > Create 'To Do' Table > Highlight list of names > Copy & Paste into Notepad to use later
  • Click the button next to each Match name
  • Close the tabs that were open when they finish processing 
  • On the 23andMe tab  > Switch Profiles if there are more than one and repeat this step for each. 
  • Refresh the 529andYou tab or close then reopen through 23andMe
  • For each person in the Notepad list:  On the 529andYou tab > Display mode:  Profile and Overlapping Segment Links > Show matches of {name from Notepad list} > Create Match Table  [Note:  That the very first time it is faster to do this for each of your profile names rather than the Notepad list.]
  • Click on button next to a Profile person match
  • If available, Ctrl click on each link saying compare {name1} and {name2} to open FIA tabs for the comparison
  • Close new FIA tabs when finished processing
  • On the 529andYou tab > Create Match Table and repeat for next profile person on list
  • On the 529andYou tab >  Show matches of All > Download CSV 
  • In Genome Mate > Import Data > Select Data Source 23andMe > Load FIA Matches and ICW from 529andYou CSV file > Import Data from CSV File > Select file named 529andYou_{date}.csv
DNAGedcom:  This is the second preferred method of loading bulk DNA segments from 23andMe into Genome Mate.  It is the best method for loading Country of Ancestry DNA segments and also updates ICW data.
  • On DNAGedcom.com> 23andMe > Download 23andMe > Enter Email address > Enter 23andMe Password > Enter 23andMe Profile Name > Check Run FIA > Check Run AC > Check Run AF > Get Data and wait for it to finish processing 
  • This loads the shared matches:  In Genome Mate > Import Data > Select Match Data Source 23andMe > Load FIA Matches from DNAGedcom CSV file > Select file named {email name}_{profile name}_23andMe_FIA.csv 
  • This loads the Country of Ancestry (CoA) data:  In Genome Mate > Import Data > Select Data Source 23andMe > Load CoA Matches and ICWs from DNAGedcom > Select file named {email name}_23andMe_AF.csv
23andMe:  This is the least preferred method for loading DNA segments as it requires the data to be manually copied and pasted from the Family Inheritance: Advanced page into Genome Mate for up to 5 comparisons at a time.
  • On 23andMe > My Results > Ancestry Tools > Family Inheritance: Advanced > Select any Compare profile > Select up to 5 With Family Members > Compare > View in a Table > Select all (Ctrl A) > Copy (Ctrl C) 
  • In Genome Mate > Import Data > Select Data Source 23andMe> Copy/Paste Family Inheritance Advanced (FIA) > Follow directions
The following loads the 23andMe CoA file:
  • For each profile:  On 23andMe > My Results > Ancestry Tools > Countries of Ancestry > Show Results for:  {profile name} > At bottom of page Download {name} Countries of Ancestries Matches (CSV) 
  • For each profile:  In Genome Mate > Import Data > Select Data Source 23andMe > Load CoA Matches from 23andMe CSV file > Select profile name > Import Data from CSV File > Select file named ancestry_finder_{name}_{date}.csv


Step 3:  Load 23andMe Relative's Surnames

This step loads the Surnames for existing Relative records into Genome Mate.
  • For each 23andMe Profile:  In Genome Mate > Import Data > Select Data Source 23andMe> Load Relative Finder CSV file from 23andMe > Follow directions


Hints and Tips

  • There are two small arrows going in a circle to the left of your profile name. 
  • Left click to show overlapping segments.  Escape to return to the original screen.
  • Right click to bring up an overlapping segment dialog
  • Choose a Relative Name in the list of matches. 
  1. Choose a relative who matches you on more than one chromosome.
  2. Right click on it to show all matches
  3. Escape to return to the original screen.
  • Some Relatives will have a small symbol (Mark ICW segments) to the left of their name.   Hover (do not click) your mouse over the symbol. 
  • A series of colored bars will show you the relatives who are in common with the one you are hovering over. 
  • These people are related but not necessarily on the currently selected segment. 
  • Some ICW group symbols are in orange. 
  • The orange color means that the segment crosses a centromere, so the meaningful length is much shorter than the displayed length.   
  • If you hover over the symbol, it will show the length of the centromere.

Getting Started using Genome Mate with Ancestry Data

Genome Mate is a desktop tool used to organize in one place the data collected while researching DNA comparisons.  Besides data storage it has many features to aid in identifying common ancestors.  It can be downloaded at http://genomemate.org/



The following guide was originally put together by George Cunningham and published with his permission.  It has been edited to reflect changes in the application.


Ancestry Getting Started Guide

Using Jeff Snavely's Chrome Plugin, AncestryDNA Helper, is currently the only way to import Ancestry data into Genome Mate.  Using the Chrome browser is required.

Step 1:  Create a Profile


  • First create a profile in Genome Mate for each kit that you manage
    • Profiles > Add new profile
  • Put in a name, any name will do, but
    • You are a good choice for the profile person.  
    • If your going to use data from 23andMe for the profile person, the profile name MUST match the 23andMe name.
  • Load a gedcom file for each profile if you have one.  If not just continue.
    • The gedcom file can be all of your relatives and more
    • Genome Mate will ask you for the name to associate with the profile person, and will strip out all but the profile person's direct ancestors.
    • The gedcom file format must be 5.5 in UTF8 format


Step 2:  Ancestry Data Collection

Using Jeff Snavely's Chrome Plugin, AncestryDNA Helper, is currently the only way to import Ancestry data.  Using the Chrome browser is required.
  • Get Ancestry DNA Helper here
  • Read about Ancestry DNA Helper here
  • On Ancestry > DNA > Your DNA Home Page > Scan > Wait for completion
This is a long process and if it stops: 
  • Open new tab in Chrome >  On Ancestry > DNA > Your DNA Home Page > Resume Details Scan and close stalled browser tab > Wait for completion
 Once the process is complete:
  • On Ancestry > DNA > Your DNA Home Page > Download Matches
  • On Ancestry > DNA > Your DNA Home Page > Download Ancestors of Matches

Step 3:  Load Ancestry Relative Profiles

Import Data page
This step creates a Relative record in Genome Mate for each Ancestry relative storing their "administered by" name and profile link.
  • In Genome Mate > Import Data > Select Match Source Ancestry > Load Ancestry Relative Records > Import Data from CSV File > Select file named Matches for {name}.csv
If you get rejected records, look for notes that have an enter or return character in their value as Genome Mate assumes that is the end of the record. Those have to be cleared before import. 


Step 4:  Load Ancestry Relative Surnames

This step loads the Surnames for existing Relative records into Genome Mate.
  • In Genome Mate > Import Data > Select Match Source Ancestry> Load Ancestry Relative Surnames > Import Data from CSV File > Select file named Ancestors for Matches of {name}.csv


Step 5:  Maintaining Relatives in Genome Mate

Since Ancestry does not provide DNA segment data, there will not be segment data displayed on Genome Mate's main page for Ancestry.  To view the Ancestry Relatives:
  • In Genome Mate > Relatives > Check Ancestry > Click on Relative name or use the Search Box to find the administered by name> Add your notes and Save

Step 6:  Obtaining Ancestry DNA Segment Data

To see the actual DNA segments for Ancestry data, it is necessary to download the raw DNA data from Ancestry and import it into GedMatch.com.
  • Click here for instructions on how to import Ancestry raw DNA data to GedMatch.  1-to-1 comparisons will be immediately available but it may be a few weeks before other GedMatch functions can be used. 
  • Click here for instructions on how to use GedMatch data in Genome Mate.


Hints and Tips

  • There are two small arrows going in a circle to the left of your profile name. 
  • Left click to show overlapping segments.  Escape to return to the original screen.
  • Right click to bring up an overlapping segment dialog
  • Choose a Relative Name in the list of matches. 
  1. Choose a relative who matches you on more than one chromosome.

Getting Started with Genome Mate using FTDNA Data

Genome Mate is a desktop tool used to organize in one place the data collected while researching DNA comparisons.  Besides data storage it has many features to aid in identifying common ancestors.  It can be downloaded at http://genomemate.org/



The following guide was originally put together by George Cunningham and published with his permission.  It has been edited to reflect changes in the application.


FTDNA Getting Started Guide

There are four steps required to get all of the FTDNA data loaded into Genome Mate.  At no time does the app ask for your raw data file.  Instead, it asks for files that have already been processed by FTDNA and can be downloaded from there.

Step 1:  Create a Profile


  • First create a profile in Genome Mate for each kit that you manage
    • Profiles > Add new profile
  • Put in a name, any name will do, but
    • You are a good choice for the profile person.  
    • If your going to use data from 23andMe for the profile person, the profile name MUST match the 23andMe name.
  • Load a gedcom file for each profile if you have one.  If not just continue.
    • The gedcom file can be all of your relatives and more
    • Genome Mate will ask you for the name to associate with the profile person, and will strip out all but the profile person's direct ancestors.
    • The gedcom file format must be 5.5 in UTF8 format


Step 2:  FTDNA DNA Segment Data Load

Import Data Page
This data is the actual DNA segments shared with relatives.  It is downloaded directly from the FTDNA Chromosome Browser.
  • In Genome Mate > Import Data > Select Data Source FTDNA > FTDNA Family Finder Chromosome Browser CSV file > Select Profile > Follow the directions
Optionally, this file along with two others can also be downloaded via DNAgedcom.  It is recommended that the Chrome browser be used as it seems to work best.
  • On DNAGedcom > Family Tree DNA >  Download Family Tree DNA Data > Enter Kit # > Enter Password > Get Data
  • Wait for DNAGedcom to finish processing
  • Find zipped file in your download folder and extract file 
  • In Genome Mate > Import Data > Select Data Source FTDNA> Load Family Finder Chromosome Browser CSV file > Select Profile > Import Data from CSV File > Select file named {kit}_ChromosomeBrowser.csv


Step 3:  FTDNA Relative Email and Surname Load

This loads the Relative surname and email addresses into the Genome Mate Relative Details record.  It is download directly from FTDNA Family Finder Matches.
  • In Genome Mate > Import Data > Select Data Source > Load Family Finder Matches CSV file > Follow the directions
FTDNA Family Finder Matches is one of the files downloaded from DNAGedcom in Step 2. 
  • In Genome Mate > Import Data > Select Data Source FTDNA > Load Family Finder Matches CSV file > Import Data from CSV File > Select file named {kit}_Family_Finder_Matches.csv


Step 4:  Load FTDNA ICW Data

In common with (ICW) data can only be downloaded from DNAGedcom and is one of the files downloaded in Step 2.
  • In Genome Mate > Import Data > Select Data Source > Load ICW CSV file from DNAGedcom> Import Data from CSV File > Select file named {kit}_ICW.csv


Hints and Tips

  • There are two small arrows going in a circle to the left of your profile name. 
  • Left click to show overlapping segments.  Escape to return to the original screen.
  • Right click to bring up an overlapping segment dialog
  • Choose a Relative Name in the list of matches.

Getting Started with Genome Mate using GedMatch Data

Genome Mate is a desktop tool used to organize in one place the data collected while researching DNA comparisons.  Besides data storage it has many features to aid in identifying common ancestors.  It can be downloaded at http://genomemate.org/



The following guide was originally put together by George Cunningham and published with his permission.  It has been edited to reflect changes in the application.


GedMatch Getting Started Guide

The very first step is to either create a profile in Genome Mate or make sure the current profiles contain the GedMatch kit # exactly as it appears on GedMatch.

Step 1:  Create a Profile


  • First create a profile in Genome Mate for each kit that you manage
    • Profiles > Add new profile
  • Put in a name, any name will do, but
    • You are a good choice for the profile person.  
    • If your going to use data from 23andMe for the profile person, the profile name MUST match the 23andMe name.
  • Put the GedMatch kit # for the profile person.  If this is not entered, no DNA segment data will be displayed on the main page for this person.
  • Load a gedcom file for each profile if you have one.  If not just continue.
    • The gedcom file can be all of your relatives and more
    • Genome Mate will ask you for the name to associate with the profile person, and will strip out all but the profile person's direct ancestors.
    • The gedcom file format must be 5.5 (not 5.5.1) in UTF8 format

Step 2:  GedMatch Names and Email Addresses

GedMatch Import Options

This function will load the first 1500 GedMatch kits with their name and email addresses into Genome Mate Relative records.  To view the data, on the Main page click on Relatives.
  • On GedMatch:   'One-to-many' matches > Enter Kit # > Display Results > Highlight data (Ctrl or Cmd a) > Copy data (Ctrl or Cmd c)
  • In Genome Mate > Import Data > Select Data Source GedMatch > (2) Load/Update GedMatch Relative Records > Paste data (Ctrl or Cmd v) > Format > Close


Step 3:  Load GedMatch Chromosome Browser Data

These functions will load GedMatch DNA segments.  The GedMatch kit # must be one that is assigned to one of the Genome Mate profile people (see Profiles) or the matches will be considered ICW data. This data will be displayed on the main page.
Bulk Load option: 
  • On GedMatch:  'One-to-many' matches > Enter Kit # > Display Results > In the column 4, check up to 200 kits for comparison >  Chr-Browse > "Here" > Highlight data (Ctrl or Cmd a) > Copy data (Ctrl or Cmd c) 
  • In Genome Mate > Import Data > Select Data Source GedMatch > (1) Load GedMatch Chromosome Browser Data > Paste data (Ctrl or Cmd v) > Format > Add > Close

  • In Genome Mate >  Import Data > Select Data Source GedMatch > (3) Copy/Paste GedMatch 1 to 1 Comparison Matches > Format > Add > Close 


Step 4:  Load Individual ICW Data

In common with (ICW) data can be loaded for individuals of interest from the GedMatch 1 to Many function for the first 1500 matches.  The ICW icon for the individual loaded will be a gold color to help with tracking.
  • On GedMatch:   'One-to-many' matches > Enter Kit # > Display Results > Highlight data (Ctrl or Cmd a) > Copy data (Ctrl or Cmd c) 
  • In Genome Mate > Click on a DNA Segment on the Main Page > Add ICW > Paste data (Ctrl or Cmd v) > Format


Hints and Tips

  • There are two small arrows going in a circle to the left of your profile name. 
  • Left click to show overlapping segments.  Escape to return to the original screen.
  • Right click to bring up an overlapping segment dialog
  • Choose a Relative Name in the list of matches. 
  1. Choose a relative who matches you on more than one chromosome.
  2. Right click on it to show all matches
  3. Escape to return to the original screen.


  • Some Relatives will have a small symbol (Mark ICW segments) to the left of their name.   Hover (do not click) your mouse over the symbol. 

  • A series of colored bars will show you the relatives who are in common with the one you are hovering over.  
  • These people are related but not necessarily on the currently selected segment. 
  • Some ICW group symbols are in orange. 
  • The orange color means that the segment crosses a centromere or other false positive region, so the meaningful length is much shorter than the displayed length.   
  • If you hover over the symbol, it will show the length of the centromere or false positive range.

William Roberts of Danbury, Connecticut

This has been a dead end for years but DNA results from Peter Robert's site indicate that William descended from or is closely related to the immigrant Peter Roberts b.c. 1665 Gloucestershire, England, d.c. 1706 Providence, RI m. Sarah Baker.  The descendants of these two matched on 23 of 24 markers which tells us that there is a 50% probability that the most recent common ancestor is 17 generations or less.  The descendant of Peter Roberts d. 1706 RI was a 10th generation descendant meaning their common ancestor may be farther back.  However, since Peter was an immigrant to the New World it is more likely he was a descendant of either Peter or Mark Roberts mentioned below:
 "The first record of the Roberts family of Rhode Island found in volume I, p. 570, the book of deeds. A house and lot in Providence and right in the commons of the plantation of Providence was bequeathed by Christopher Unthank to Thomas Roberts, June 1663. Thomas Roberts died about 1679, and his administrator, Captain Richard Smith, represented his nephew and heir, Christopher Roberts, of Arlington, Gloucestershire, England, December 5, 1679. There was recorded June 6, 1681, by Captain Smith, as attorney for Christopher Roberts, the title to four acres laid out to Thomas Roberts, deceased. (Book of Deeds I, p. 59). About the same time Peter and Mark Roberts appear at Warwick, Rhode Island. There is reason to believe that they were brothers, nephews or sons of Christopher, and that Peter had the land at Providence. Mark Roberts married, January 1, 1682, Warwick, Mary Baker, and had: Mark, born April 10, 1683; John, December 4, 1685. John had ten children at Warwick, and the name Christopher, which appears in all the families, presumably for Christopher Unthank, mentioned above, undoubtedly a relative." [Ancestry.com. New England Families, Genealogical and Memorial [database on-line]. Provo, UT, USA: The Generations Network, Inc., 2004. Original data: Cutter, William Richard. New England Families Genealogical and Memorial. Vol. I-IV. New York, USA: n.p., 1915.]

This chart was extracted from Peter J. Roberts site.  It shows that the descendants of William Roberts of Danbury, Connecticut and Peter Roberts of Providence, Rhode Island match on 34 of 37 markers.

“34/37 You share the same surname (or a variant) with another male and you mismatch by three 'points' --a 34/37 match. Because of the volatility within some of the markers this is slightly tighter then being 11/12 or 23/25 and it's most likely that you matched 24/25 or 25/25 on previous Y-DNA tests. Your mismatch will most often be found within DYS 439 or DYS 385 A, 385 B,389-1 and 389-2 from our first panel of 12 markers, or within the second panel: DYS #'s 458, 459 a, 459b, 449, or within 464 a-d. If you matched exactly on previous tests you probably have a mismatch at DYS 576, 570, CDYa or CDYb in our newest panel of markers. Your mismatch is likely within the range of most well established surname lineages in Western Europe. “ [http://www.familytreedna.com/GDRules_37.html]

In fact, the mismatches occurred on DYS 439, DYS 570 and CDYb.  All three of these have a faster mutation rate. 
Unique Characteristics of DYS #439“The unique characteristic of marker DYS #439 has to do with its rapid mutational rate. About 25% of the mutations in the first 12 markers take place in marker #439...thus indicating a faster mutation rate than most of the others. Therefore, if you find a mismatch on marker #439 between 2 participants, and all other markers match, then you have a very good likelihood of a connection and can discount the mismatch of this marker in your analysis. Your conclusions may also be strengthened by good research and documentation if it indicates possible relationships between the two participants.”  [http://www.hilldna.com/mutations.html]
DYS 570 & CDYb“Note that the 37-marker scores … do not include markers DYS607, DYS576, DYS570, CDYa, or CDYb ( from FTDNA's third panel of markers 26-37 ). These markers have very high mutation rates and no modals are to be had at this time. They are very useful for comparison between persons who are suspected to be related but they are not very useful for identifying one's subclade.” [http://www.lrbcg.com/jtCullen/CullenDNA.htm]  

Speculation

William Roberts married Ann, widow of Andrew Sherwood  23 Mar 1762.  Ann's first child, Daniel Sherwood was born 1746 placing her marriage about 1745 and her birth sometime before 1727 if we assume she was age 18 when she wed Andrew.  William and Ann Robert's last child was Sarah born in 1770 indicating when Ann reached the end of her child bearing years at around age 50 so I estimate she was born 1720-1727.

If William was about the same age or perhaps younger, his age is bracketed between 1720-1740.  Peter and Mark Roberts married in 1682 and 1685, respectively.  This means there were only 2-3 generations between William Roberts of Danbury CT and Mark/Peter of Providence RI meaning that William would be the grandchild or great grandchild of Peter or Mark Roberts.

Piecing together descendant information for Mark and Peter Roberts from information posted online gives this:

 A Mark ROBERTS d. 17 February 1767 "in his 84th year" [so b. c. 1683]. This Mark ROBERTS is buried in "Ticknor's Woods" Sharon, Litchfield Co., CT. (Sharon is very near Amenia, formerly Nine Partners, Dutchess Co., NY, where a lot of Roberts families lived in the 1700's.)
Also buried in Ticknor's Woods is Nathaniel ROBERTS who died Jan. 16, 1766 "in his 55th year" [so b. c. 1710-1711]. A history of SharonCT, says that this Nathaniel Roberts moved to Sharon in 1759 from Salisbury, Litchfield Co., CT. When Nathaniel died in 1766, according to the history, he left sons John, William, Lebbeus, and Amos.

Given the DNA evidence that William belonged to the Providence RI Roberts who settled in Duchess Co. New York and from the proximity of Danbury to Sharon, Connecticut, I suspect that William was son to Nathaniel and am seeking DNA evidence to confirm or deny.
