Unique... for a surname. My name is Alexander Benjamin (and, scarily enough, I once went to school with a guy named Benjamin Alexander). Everyone confuses my surname for my first name and calls me Benjamin... to which I silently rage. Somebody please explain why the fuck, in a name made up of two first names, the second one given is more likely to be the first??? Why is Benjamin Alexander more probable than Alexander Benjamin????
EDIT: Apparently, as of 2000 my surname is 0.014%, or 1/7402 people in the US. Guess it's not that rare, but I've never met another Benjamin other than one of my relatives in the UK.
Also, my mother's maiden name was Turnsek, which Wolfram Alpha doesn't even know exists. Her father's Austrian, though, and it may be more common over there...
