I prefer [name]Annabelle[/name], love the name!
I prefer [name]Annabel[/name]. [name]Annabelle[/name] is too fussy and looks like a combo of [name]Anna[/name] and [name]Belle[/name] to me, but [name]Annabel[/name] looks like the legitimate name with separate origins.
I love [name]Annabel[/name]'s connection with the poem, but I’ve always preferred [name]Annabelle[/name]. My teacher’s 11 month old is named [name]Annabelle[/name] [name]May[/name]. :] (I’m from the Seattle area)
