Most people labeled Negro's are not even really african decendants in american, most people labeled that in this country were really the colored people that white people re-named from their true state. Indian "Sitting Bull" once said that his ancestors originally came from a place called Mesada, Israel. So I would suggest that one of the 12 tribes if Israel were in fact colored people of america or colored native americans, due to the writing concerning burnt brass as a skin color stated in the bible.
