Hey, that's my name!
It's the name of one of the wise men from the New Testament. Persian/Babylonian origin, I think. As for the actual meaning, I've heard definitions ranging from Splendid Prince to Defender of the King. I've also heard it means "God Save the King" in Greek. It has to do with nobility, in any case;-)
