Edited from a conversation with a friend:
mary: so among the things I’ve found out: I’m about 1 homeopathic amount Jewish, same goes for Naragansett (and related) native Americans from CT/RI and Long Island, and about as much Nottoway Cherokee, which is different from “real” Cherokee. All in the range of 13thish or 14th great grandparents.
mary: it’s academically interesting, but once you go far back you have hundreds and hundreds of grandparents, so it’s not especially relevant.
mary: just interesting.
mary: 131072 grandparents at the same level as the jewish and the native american ones
mary: (just did the math)
So for my nieces and their children? Double that number. Then double it again for the kids.
But it’s still interesting.
