I usually use baby name sites of behindthename.com to find names with meanings that are relevant to the story.

For example, the main character in the novel I'm currently writing is named Teagan, which comes from an older word that means poet, which fits because she is a literature major, and a "Bard" (this has a very specific meaning in the story).

Sometimes I just try to come up with a name that has the kind of feel I want to the story. For example, Sally, who is one of Teagan's roommates, who is very 'normal' and... well, boring isn't quite the right word, but it gives the right idea.
