What's in a name?

I was watching tv last night and the news was talking about the winner of the UK's version of some talent show that I don't watch here in the states. The guy is an opera singer and his name is Paul Potts. Now, when the anchor first said the name, I was thinking to myself, "hasn't Pol Pot been dead for a few years now?" So I can't help but wonder what made this man's parents name him Paul. I mean, would the Schmalins name their kid Joseph? I hope not.
