Recognizing that I am halfblood Choctaw:
My maternal grandfather, a halfblood circuit-riding preacher, had the last name of Funderburk. This is the "Americanization" of the family name "Von der Berg"; yep, its German.
My paternal grandfather, a halfblood farmer, had the last name of Rowe -- which is the English spelling. Subsequent research determined that it was originally Roe -- the Irish spelling. His forebears changed it to the English spelling because of the signs in The New World that read "Irish need not apply." Even earlier than that, it was Ruadh ("REW-aahh"), an Irish word meaning "red" or "red-haired". This is also the root-name for Rowan, btw.
There are a LOT of Biblical names among my ancestors: Noah (2), Ezra, Benjamin, Ruth, etc. However, perhaps the oddest are Cleta Belle and (given that my ancestors lived in Dixie) Juanita.
