Jasper as a boy's name is one of my GP. It's so gentle and scholarly. I once told my friend about my love for the name, though, and she said that she would disown me if I ever named my son that. I don't know, is it really so awful??
I actually quite like month's names for girls as well...I once saw a movie with a girl character named October, and totally loved it. I thought
Toby as a nn would be so neat. And then of course there's January Jones, the actress on Mad Men; that is awesome too.
February is one that I hadn't considered, though - Febs or Febby are adorable nicknames for it. I like it!
