I really like Nicholas for a boy. I haven't heard it much lately.
That's our boy name, should we ever have one, named after my much loved and cherished grandfather and it's nice because it isn't so common anymore, but still kinda timeless.

Your names are beautiful, PZ. It's so great once you "know". We had our names for the longest time too and they never felt wrong to us. Our daughter's name is in the top 5 most popular names now though, wasn't when we picked it, but we loved it too much to change it.
