I like the name and Whitaker comes to mind first for me. But then Gump... Have you read the book? It's much better than the movie (and completely different)
Me too. First thought Whitaker. I like the name, my first thought was its a really strong name that would carry well as an adult. But I do think that kids will do the whole Forrest Gump thing, kids being kids.

And yep, the two Forrest Gump books are awesome
