I am a genealogy buff, and they are many white people with minute traces of African ancestry DNA. Most black Americans are partly white, but the same is true to lesser extant in reverse.
“African” can mean a whole lot. It doesn’t exactly equate to “black” either. Northern Berber tribes & Copts have A LOT of Caucasian characteristics (green/blue eyes & light skin).
Germanic Visigoths and Vandals actually had Kingdoms around Morocco, Algeria & Tunisia for hundreds of years before the Mohammadan conquests. Not to mention Roman & Greek colonists & traders flooding North Africa for at least 700 hundred years (or there about).
That is absolutely correct. My wife had an ancestry search done by her daughter and found she had a black ancestor in her lineage from several hundred years back in England.
So I (jokingly) asked her if she wants to claim some sort of affirmative action benefit. We have no idea what kind, but there's no harm in trying. lol
