Very simple, just say where you're from although i don't force anybody to share the exact state or city in which they currently live.

Also people may add their foreign origins like having a chinese father and an italian grandmother.

I'll go first : I am French but i'm from a portuguese familly.

United States for me, Polish and Welsh descent but at least my mother's side were part of the original Pennsylvania(?) colony.

I'm from England and My nan on my dad's side is Welsh.

I'm from Scotland. Both my parents are Scottish, but we have Swedish and English blood further back as well.

Midwest USA, lots of Dutch ancestry

Germany :D
