The one thing to watch with Isabella is the whole twilight connection. Might not be a big issue for you, not a fan of the books/movies myself, But if DH is obsessed with names that could be teased then people might go on about that?
I did mention that because intially thats why i shied away from Isabella, but surprsingly he pointed out that Twilight won't be popular forever! We'll just make very sure not to shorten her name to Bella, which is perfectly fine with us because even though I love Bella and Twilight really ruined it for me we had a dog Bella, so issue solved!
