Isabella or Isabel or Isabelle?

[Hope88]

I know Isabella is very popular. I was wondering whether Isabel is too? I like the name Bella. Can I have a nn Bella if her name would be Isabel?
Ideally I would like to choose the name which is used the least.
Which one do you like most?

BTW I have a friend who called her daughter Annabella, and she goes by the name Bella.

DD is an Izabelle shes 2 and her little friends call her Belle or in one case Tinkerbelle :) .

The only problem with it is that people invariably spell it in various versions but the right one but I think that will happen whatever you chose.

Isobel

Isabelle, think thats the nicest, Isobel seems a bit 'old great aunt' to me

How about Mirabel - Bella?
