What is gained by being/claiming Native American/Indigenous? They don't see you as kin.
And I find it VERY hard to believe that someone traces their tree -- and they are BLACK -- and think they don't have any African ancestors. I say to that -- you aint looking hard enough-- or at all. Plus, records don't go back that far. UNLESS, you have Estate/Will papers for all of your ancestors -- and that ish is IMPOSSIBLE.
First off, when you research the Census -- most of us are cut off at 1870 -- so you are not going to see AFRICA as their home. But, MANY, MANY census records straight up list Africa as many of the former enslaved home.
It's literally hundred of THOUSANDS of records that list AFRICA for Black people. From the time period of 1700-1899.
Our people were African -- look at their faces. They were descendants and "fresh off the boat" africans.
