Is it too crusty old-man or nerdy? DH mentioned he liked it the other day, so I thought I'd garner some popular opinion. What do you think? For what it's worth, we're having twins, and in the event it turns out to be two boys (won't find out for another week and a half), his brother would be Felix Peter.
Gray would most likely be the middle name (it's a family name), but that's not set in stone.
Other potentials are Maxwell, Robert, or Isaac.
