Many white people were literal slaves around the same time (in the 1800s and before). Look into the Barbary slave trade. Over 1 million white people were held as slaves in Africa. Even some Americans were held as slaves in the Barbary Coast.

I guess I don't think where our ancestors came from is very important. I only know where my ancestors lived about 200 years ago and it is just general areas not any specifics. I don't know anything more than that. This is quite possibly about the same amount of years as many blacks whose ancestors came over during the slave trade.
