Family Tree DNA This organization is running several voluntary test programs for family groups and ethnc groups. By looking at the list, I learned that the A2 blood group which I have (by the HLA Blood Marrow Donor factors) is affiliated with people of mixed Aerican Indian blood of the Canadian Maritimes .. ie the Mic Mac people.
I happen to descend from three or four generations of Scottish ancestried Prince Edward Islanders & Cape Breton Nova Scotians.
HLA Type] :
A2, A30, B13, B44, Cw5, Cw6
The mix is referenced like meztizo as metie and is a colective blood grouping for the people of Acadie the old Arcadians.
Mine may likely come from mixes in the MacEachern & McCormack backgrounds .. or something on my paternal side [which may have a New Brunswick ancestress]; or the realization of the MacPhee legendary ancestress who may be an Eskimo or or other Artic Circle aborigine.
