Was Hercules a Brother?

Here's a strange idea for Black History Month. According to Josephus - of quoted, well respected, 1st Century Roman & Jewish historian; he reports that Africa derived it's name from descendants of Abraham & Keturah and that Hercules' buddies were Africans. And, dare I say it, Josephus reports, referring to the account of an earlier historian named Cleodemus, an account confirmed by another prominent historian named, Alexander Polyhistor; that Hercules married an African woman. Here is the direct quote:

"Abraham after this married Keturah, by whom six sons were born to him; men of courage and of sagacious minds:

...Abraham contrived to settle them in colonies; and they took possession of Troglodytis, and the country of Arabia the Happy, as far as it reaches to the Red Sea. It is related of this Ophren, that he made war against Libya, and took it; and that his grandchildren when they inhabited it, called it (from his name) Africa...there were many sons born to Abraham & Keturah; (241) nay, he names three of them, Apher, and Surim, and Japhran: that from Surim was the land of Assyria denominated; and that from the other two (Apher and Japhran) the country of Africa took its name; because these men were auxiliaries to Hercules, when he fought against Libya and Antaeus; and that Hercules married Aphra's daughter."
