That’s hard to say. My DNA shows 73% England, Wales & NW Europe; 13% France and the rest is split between Acadian and Native American Indian.
My great-grandmother’s family on my father’s mother’s side is literally from England (Mayflower descendant, here). My mother’s father’s side, though, they come from the UK back in the 1600s, but the subsequent families were born here in the USA. Her mother, though, may have come in from the UK in a later era. I haven’t gotten that far to know yet, but understanding the geographic history of Nova Scotia leads me to that conclusion.
My father’s side, however, is Acadia/Mi’kMaq to the 1600s and then from France earlier than that. My father was 2nd generation USA born.
The lower the % ethnicity, the higher up on the ancestry chain, I do believe, and then it depends on which sides your DNA are being drawn from. Remember - we get our DNA from BOTH sets of parents.
Secrets - oh yeah...they’re everywhere. How far back has your brother reached on both sides?
the late 1700’s from what I understand. There is no record of anyone coming from Scotland-Ireland.
