Wait… wtf is “United States” in KY and TN and also… fuck yeah 💪 

 Yeah, I don't know, and I forgot where I found it. But yeah, they just spawned into the US in those spots I guess.  

 Funny as hell, but doesn't look real.

IDK how you would reliably distinguish (genetically) Dutch/Flemish/German/Norwegian from eastern England without searching parish records as a check.

Ditto for Irish vs Welsh or Scottish. Or Liverpudlian. 

 Damn. Can legit see the Trail of Tears and slavery on the map.

That said, this would be the most-common largest ancestry portion. African-Americans average 25% Scotts-Irish, so Scotts-Irish is probably more accurate, for the South.

Mexican-Americans are also usually German or Spanish, so that is also inaccurate. Same with Oklahoma, since most of them probably also have  mixed ancestry. Etc.
