Most Guessed: Irish
Favorite Guess: French, Spanish, Danish. My uncle Jake (Jakub) is Danish, but we are not blood-related.
Real: Dominantly English, Irish, and Scottish, with some German via my maternal grandmother. If there's anything else, it's a very small percentage.
Guessed Correctly by: All six votes had at least one of those four in it, but mutualmitten's was the only one 100% correct (said English with some Irish).
