No he's not related to the king Abed, he is a southerner like me, from a city beside Sebha called El-Shati, he's from a tribe called the Megrahi's, yes the same tribe as Abdul Baset El Megrahi who is also from Al-Shati.
And speaking of Al-Shati, i'm from Al Shati too
and yes Geddaffi has a son called Khamis. He has 7 sons and one daughter. Khamis is his youngest son, and he's a criminal just like his father.
