I'm not a fan of -bel names, they're too 'much' for me. However it would be nice to see, and better than '
Chris' and is very unexpected.
I really like
Christabel Diana, it's well grounded.
Christabel Georgina is also lovely.
I think if you want to play on that tinkling bell effect I'd go for some alliteration:
Christabel Clare /
ClaireChristabel CamillaChristabel Catherine (or preferred spelling)
Christabel CatalinaChristbael
CelandineChristabel Claudine
Or may I also suggest:
