Help me find the 'perfect' girl's name?

[starcrossed.livejournal.com]

I'm having trouble finding a girl's name I like.

I'm 95% sure on Oliver Henry for a boy (though other possible contenders could be Charlie, Max, Toby, Frankie or Jack.)

I'm quite a fan of 'nickname' type names like Evie, Molly, Holly, Maggie and I also like Gabriella and Phoebe but none of these seem quite 'perfect' (when I put Oliver and Henry together I thought 'That's the one!' but haven't had a similar moment for a girl's name yet.) Selena is also a very traditional family name (used for 120 or so years) I would consider.

Any thoughts?

ETA: Unless it really clashes with a first name I love, I'll be using Gwendoline (my Nan's name) as a middle name. Rose is another family name that could be an alternative middle name.
