Christian is one of my favorite boy's names. I personally think it sounds more masculine. But it could work on either. I've seen a few girl's named
Christian, and it's nice.
I don't know what nn's she'd have,
Christian doesn't seem as likely to me to be shortened as say
Christina or
Christine would. I do like
Chrissy, though.
I'm not good at combos but here are a few ideas:
Christian AbigailChristian LorraineChristian YvetteChristian HelenaChristian Serene
Christian MarinaChristian JanelleChristian LianneChristian AlexandraChristian SiennaChristian MarianChristian GuinevereChristian MercedesChristian Gloria
