My kids always were proud of the fact that through my mother's side of the family they are related to 5 former US Presidents. They also have relatives that came over from England and took covered wagons across the United States.
I figure if it bothers you that much have a talk with the teacher and ask for an alternate assignment.
well good for your kids. not everyone has such a stunning family tree and i think it is unnecessary when you consider how broken up many families are. give me a break.
