“Alma was born in 1960. So it doesn’t seem logical that they would have the same mother and BHO be born in 1960”
Auma is 100% African,judging by her pigmentation, while Barry is obviously about 50% Caucasian so they can’t be children of the same two parents, IMO.
Did you know that black people get darker and lighter, depending upon exposure to the sun, just like anybody else does? The sun is very, very strong nearer the equator. People would categorize me today as “white”, but when I was a kid and in the sun all the time, I was called the “n-word”. Just because Auma looks darker than Barry, it doesn’t mean she has any more “African” ancestry.
