John Paul reminds me of the former Pope
For me, that's a really good thing :) I know others would disagree, but it would be a name after JP2.
I have a nephew named John Paul (after the Pope as well), and I love it. Also, my nephew loves it. :) He is three. For Christmas, I sent him a really sweet children's book called "Lolek" - it's an illustrated story of the pope's life, focusing on his childhood. My nephew *loves it,* and is very proud of his namesake. If for any reason he didn't want to be associated with the Pope (don't anticipate that as his father also has this name and loves it as an adult), he can go by "John."
