Sorry to say, your forefathers made the mistake of not being jammed into ghettos, engaging in violent street brawls and organizing themselves into brutal criminal enterprises. They quite sensibly arrived and said, "Hey, where can we grow something to eat or sell?" and then left the cities.
My German cousin (I'm 1/2 that) ran one of this country's (then) largest cities and just missed out on getting elected to the Senate. Half the family lived in the sticks and the others in the cities. All that "race mixin'," couldn't make up their minds. :-P
