A few commenters have posted that Trig and Tripp’s names aren’t on the list for the Alaska Permanent Fund checks. That information is false. The applicant list at http://www.pfd.state.ak.us/applicantinfo/index.aspx which you have to download to your computer and open does list both Trig and Tripp Palin in 2009 and 2010.
I did find something that was interesting. In the 2010 list Tripp’s last name is Johnston-Palin. In 2009, it was just Johnston. So evidently Bristol must have had his name changed. Was that to get back at Levi or did Bristol want both of her sons to have the same last name?
