WADR to Blam, Cleopatra was Macedonian, not Greek. The identity of one of her grandmothers isn't known, but the Macedonians were a little nutty about "ethnic purity" (to borrow a phrase from Jimmy Carter), so it's generally believed that she was a Macedonian too. I know the first names of a number of my female ancestors, but don't have a clue what their maiden names were. :')
One of those photo URLs I posted was this:

That's the image accompanying an essay by none other than Mary Leftkowitz, entitled "Not Out of Africa", hosted right on the Martin Luther King website. The essay is similarly titled to the book of that name, which refutes claims that Greek philosophy and so on was stolen from Black Africa.
Remarkable as that is, you won't believe what's behind door number three...

Ah! I see. That's not the official site at all, not by a long shot. It's another Stormfront, uh, front.
