What's in a Name?

I've perhaps dropped a post or two so far about how interesting I find the names Sarah and Todd Palin chose for their children to be. Today, I was pleased to learn more via People Magazine via Andrew Sullivan about the backstory on Track, Bristol, Willow, Piper and Trig:

"Sarah’s parents were coaches and the whole family was involved in track and I was an athlete in high school, so with our first-born, I was, like, ‘Track!’ Bristol is named after Bristol Bay. That’s where I grew up, that’s where we commercial fish. Willow is a community there in Alaska. And then Piper, you know, there’s just not too many Pipers out there and it’s a cool name. And Trig is a Norse name for “strength.”
