Question:

How can we discover our ethnicity?

whenever i suggest that there must be MORE to my ethnicity, my mother always insistintly disagrees and says that we are whatever her grandmother was (because thats as far as she can go). well, i dont think her grandmother just popped out of the ground from somewhere. there is definitely more...how can we find out?

Locate someone of the same and talk to them.
