My preferred spelling is
Isabelle w/
Isabel in 2nd place. Don't like
Isobel at all because the o really looks out of place. It's somewhat boring and overused, but otherwise a decent name... in which case the mn spot is prob'ly preferable at this time... but it can go either way depending on what it's paired w/ since the flow would be important to some people. Choose which side of these names it should go on.
