My two sides are wildly different.
On my fathers side, I am 3rd generation American.
My father's grandparents all came over from Belgium. His parents still speak the language, and my dad and his siblings are the first generation not to have crazy-strong accents.
My mother's side is just the opposite... I'm 12th generation or something like that. The line of the family tree we can trace most easily is from England, they came over in the 1720s or somewhere around there. We have hints of a few of the other lines (the one we've traced is my maternal great-grandfather's line) that all seem to come from England or the greater Isles, with one stray line that came from Luxembourg
