Traditional Research

  • Recreating the genome of Abigail Courtney
    • Visual phasing of the 4 Roberts-Murphy siblings (children of Ted);
    • Inferred mapping via 2 descendants from Roberts-Murphy sibling 5;
    • Visual phasing of another 4 Robert-Courtney siblings (grandchildren of Jimmy);
    • Determining Genetic Groups
      • Eliminating the segments inherited from Abigail Courtneys mother Abigail Paice;
      • Interrogating remaining segments though traditional genealogical research to identify common ancestors within triangulated groups.

    At a recent Society of Australian Genealogists hangout I presented a session on my DNA journey since 2010. It includes details of the extensive genetic research into George's origins. Click here to view.
