Evidently 'Guerre' means 'war' in french

I just noticed today in French class that the word "guerre" means war. I asked my professor about it (who is French), and she thought it was strange that someone's last name was War. I know that he came from a war and everything, but it still seems like an odd choice for a name. Anybody with any French background know of any context or connotations that I am missing out on, 'cause it just seems strange.
