When you have a Muslim for a father and step father, and they are permitted under Sharia Law to have more than one wife at a time, you wind up with a heck of a lot of half brothers and sisters.
Adopted? I don’t think so. Probably a daughter of the father or step father with one of his wives who passed away.
This is all so creepy, and sad. And dare I say, downright un-American?
It does resemble, dare I say, the Bin Laden clan.
