Are you looking for another hyphenated name?

[SteviebunsBottrittrundle]

Going with the Irish theme:

Aoife
Ailish
Sorcha
Catriona
Orla / Orlaith

If looking for hyphenated (sorry if these are pants - I'm not great with hyphenated names, but I like these)!

Marie-Claire
Seraphina-Joy
Aurelia-Jane

I have an irrational dislike of anything hyphenated with May / Mae and it does seem quite well used, so I would probably avoid that personally.
