Here is an article about Sarah Palin's kids' names. It talks about name trends in "blue" versus "red" states.
By the way, the female Colin in Colin's class never appeared. We noticed on the first day that there was no longer anything in the classroom with the other Colin's name on it and Colin says that there isn't another Colin in his class. So we shall never know if there actually is a female Colin out there. How many times can I type Colin in one paragraph?
Oh, and Riddek seems to be Colin's new best friend.
