My mother told us we were 1/32nd, since my grandfather grew up on the White Cloud reservation near Missouri somewhere. She did the DNA test.
Turns out her father wasn’t her biological father. Oops.
I’m severely Irish, as a result. My dad nearly full, and my mom was nearly full Irish.
The Irish were always the last one listed on the signs:
No Dogs
No Ni****s
No Irish
I’ve got that sign, unredacted, in my office at home.
Wow, Yes, DNA can provide surprises. There is a rumor in my family that my grandmother had an affair and the man listed on my mother’s birth certificate is not valid. As you put it so well, oops. But at this point I cannot tell. The DNA evidence is not enough to make a clear call. In this instance it is not Indian blood that is in doubt, that was on my father’s side; but this would affect the level of Jewish blood. (which come to think on it is low, but I also don’t know the level in my grandfather — if he is my grandfather).
