Genetic Groups
Abigail Courtney (m Roberts) 1871-1928 |
As I have continued to identify the segments inherited by my family from Abigail, it has been an ongoing challenge to determine whether she inherited each of the segments from her father George Courtney or her mother Abigail Paice.
The overall aim of this exercise is to identify segments inherited from her mother to exclude from the analysis. In this way, we should be left only with segments inherited from George with all remaining triangulated groups providing clues to his origins.
Defining Triangulated Groups - Paice or Courtney?
This page is an attempt to summarise all the outcomes of each Courtney-Paice triangulated group on one page. The many relevant groups are slowly being added to the page, along with the common names and/or places associated with each group. Clicking on the links (TBA) shown in the potential ancestors section will take you to a blogpost with more information about the triangulated group or potential shared ancestor.
You can view my progress on the genome of Abigail Courtney at DNA Painter. For her most current chromosome map click here.
NOTE: 'Not yet triangulated' in the context of this post means at the chromosome level, due to unavailability of chromosome data at AncestryDNA. Tree triangulation has been achieved.

- C21_A_M158:
- C21_D_M020:
- M103: Pittman/Jackson, North Carolina; 13 testers identified includes 4 members with triangulated chromosome data (2025);
- M117: Cox/Burkaver, Texas. Initial TG to this couple, 2 testers. However several other Burkhalter matches lead back to Michael Burkhalter b1694 of Switzerland. 6 testers, 3 with chromosome data (2025).
- M128: Newcombe/Reynolds, Canada; 10 testers identified, only 2 siblings with chromosome data (2025).
- M169: Rudd/Webster and possibly Webster/Kent: both Middlesex England, 7 Rudd/Webster testers identified includes 2 members with triangulated chromosome data. Only two close Sullivan/Trodd matches and no other tree triangulation for Webster/Kent but they are in same TG as known Rudd/Webster matches (2025).
- M205: Belson/Pyecroft, Norfolk England (later of Michigan). This is the stronger genetic cluster that eminated from the Rich/Sweet couple. Beslon/Pyecroft is on the Rich side, but the Sweet line has a Newberry connection that remains of interest. 15 testers in all, 3 members with triangulated chromosome data (2025).

Abigail Paice (wife of George Courtney) 1845-1928 |
List of unidentified paternal sides from Visual Phasing process, unclear whether they were inherited from Edward Roberts (Baker-Dye/Laundon) or Abigail Courtney.
- C03_ Now resolved
- C04 _Now resolved
- C12_ Now resolved
- C13_ Now resolved
- C17_ Now resolved
- C18_ Now resolved
- C22_Still unresolved ten years on.....! However, P1 may be Courtney as it includes descendants of the Burkhalter group from C02. So far, we know P1 is NOT Paice, but it could be Dye, Laundon OR Courtney .. as at 2025).
