He has great taste! The only name on the list I don’t like is [name]Virginia[/name]. My favourite is [name]Georgiana[/name] with [name]Katherine[/name] or [name]Elizabeth[/name] as the middle. Also, I love nn [name]Ginny[/name]!
Your husband has lovely taste in names! If you worry about [name]Georgiana[/name] being to similar to [name]Annabelle[/name], what about [name]Georgina[/name]? You still get the (amazing) nickname [name]Ginny[/name], and it would still honour your husbands great-grandma, without the repeating sounds.
Exactly my thinking. All nice choices. 
I think it’s fine! I know a girl who’s name is [name]Anna[/name], and her sister is [name]Anissa[/name], and if they can do that, then there is no problem with [name]Annabel[/name] and [name]Georgiana[/name], especially if they go by [name]Belle[/name] and [name]Ginny[/name]. 
To be honest, [name]Georgiana[/name] is a mouthful. [name]Georgia[/name] is cute and not that much of a stretch away from [name]Georgiana[/name]. Plus, it still can honor your great grandma.
[name]Annabel[/name] & [name]Georgia[/name], very cute!
I love [name]Tabitha[/name], its lovely and cute at the same time. But I’m not sure how [name]Annabel[/name] and [name]Tabitha[/name] go together.
[name]Katherine[/name] is quite plain and ordinary compared to [name]Annabel[/name]. But [name]Bell[/name] and [name]Kate[/name] go good together.
[name]Annabel[/name] and [name]Elizabeth[/name] make a lot of sense together, as they’re both feminine as they come. [name]Elizabeth[/name] is very common though, especially compared to [name]Annabel[/name]. I personally thing [name]Annabel[/name] and [name]Lilibeth[/name]/Lilabeth sound amazing together. [name]Bell[/name] and [name]Lily[/name], or [name]Bell[/name] and [name]Lila[/name].
[name]Virginia[/name] is an interesting choice, and its kind of a cute, less common route rather than going for [name]Victoria[/name]. Not sure how it goes with [name]Annabel[/name] though. Plus, nicknames could include [name]Virgy[/name], [name]Gin[/name], or [name]Gia[/name]; not sure if either of you would go for that.
I think [name]Annabel[/name] and [name]Katherine[/name] are gorgeous together!
