I can only speak from experience. For years when I was a little girl I asked
my mother if I had any "Indian" blood in me (well, that's what we called it
in the 50's) and for years she said "No", yet no matter how she denied it I
was sure it was there. Finally, in the late seventies one of my cousins did
extensive research on the family history and found that the one
great-great-great grandmother who had allegedly been French and had married
the great-great-great grandfather at Notre Dame was really a Native North
She also had insisted that the family was Irish, that our branch of the
Stewarts were Irish, and that we had no Scottish blood in us, no matter how
I loved the bagpipes and felt as if there were Scottish blood in there too.
Finally, after an examination of birth records showing family given names to
be filled with Frasiers, Douglases, Alisdairs, and a bevy of other Scottish
names, most of which were surnames used as given names, it was finally
discovered that well, yes, we had spent several generations in Ireland, but
before we had moved there the family had indeed been Scottish.
