Lily who?

While I do know a Lily or two, its not a name I come across very often. But when I read Whales on Stilts and realized that Lily was the main character, something clicked. There's Lily Kane, Veronica Mars' best friend, and Lily Moscowitz, best buddy of Princess Mia in the Princess Diaries I've been listening to. And I have the nagging sense that there was another Lily recently as well. Where have they all come from?
