[name_m]Grant[/name_m] is a great choice! It’s funny you mention your concern about [name_m]Isaac[/name_m] – I just learned yesterday that it is the most commonly changed name on birth certificates because of spelling errors (Issac –> Isaac). But that being said, it’s still on my list, and I wouldn’t let it stop me!
