Thor

Thor is the powerful name of the Norse god of thunder, strength, and rain would make a bold statement. Long a comic book staple, Thor has now invaded the big screen, and could land on birth cerificates as well.

Thor Heyerdahl was a famous Norwegian anthropologist/adventurer, author of the book Kon Tiki.

In Norse mythology, Thor was the son of Odin--another crossover name possibility--who was sometimes referred to as Bjorn in Old Norse poetry. Tor is a popular variation (which is also the Hebrew name of a bird that symbolizes the arrival of spring).
