I like
Grey better for a girl, but I'm assuming it's not only the name
Gray, but that particular spelling that has meaning. :o) There's absolutely nothing I can find wrong with
Gray in the mn slot, though.
I'm really diggin'
Aurelia Gray, but it may be too rhymey for you.
Others from your PNL that I really like are
Flora Gray,
Daphne Gray,
Elsa Gray,
Lavinia Gray,
Penelope Gray &
Ursula Gray.
