I'd welcome any thoughts on the name Christobel with Christy (-ie?) as a possible nickname.
One issue is that my sister's long-term partner (F) is called Kristie. They live in France so we don't see them all the time. Would this put you off? I don't care at all as they're different names and anyway Kristie is a lovely person so it's not a problem, but I just wondered whether it would seem odd to others (would probably do it anyway but it's nice to know!)
