Help with some math please. Indian Heritage

[JoePhilly]

12. My mother told me that one of her grand parents was part ...

... American Indian.

My mother's mother (my grand mother) was raised by her Aunt (my grandmother's mother died shortly after my grandmother was born).

So the woman I knew as my great grandmother (who was actually my grand mother's Aunt), said that her grand mother (and thus my grand mother's grand mother) was an American Indian.

I had no problem telling people that I was "part" American Indian.

Or that I am, via other grandparents, also French, Irish, Scottish, German, and English.

I'm, a mutt.

I bet Trump hates that.
