Well Isabella is VERY popular because its such a beautiful name, in saying that so is Aliyah though I dont hear it alot. Depends if you want a popular name or not?

We had Isabelle/Isabella on our list but decided Annabelle suited our princess more and that it wasn't as common. Its well known but there isn't an Annabelle in every room you walk into

Thats our way of thinking, hope it helps
