When Trig was born in April, his father told the Anchorage Daily News that "Trig" was after a great-uncle. It's also an Old Norse word meaning "true" or "trustworthy." Paxson is an Alaskan town noted for snowmobiling, and Van is from the name of the rock band Van Halen. As young people in the '80s, Todd Palin has said, they thought Van Palin would be a really cool name.

Palin explained his other kids' names in a recent interview with People magazine: "Sarah's parents were coaches and the whole family was involved in track and I was an athlete in high school, so with our firstborn, 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."..
