Sadly I couldn't tell you with total certainty. My mother's side has been on the north american continent longer than the country, and we kept records at one time, but most of that was lost in fire arround 1890.
I do know there is quite a bit of European mixed with Native American (Cherokee, Iriqois, Potowanamee. Please excuse the spellings), but we've never really been too picky about who we marry, so nobody really knows beyond English, Irish, and Scotish from the European side, and the Native American contributions.
