I really like
Corinne.
Ellen is ok but it seems on the dated side to me. I dislike the name
Robin because it reminds me of robbing.
Geoff is nice but I think it's better as a short form of
Geoffrey.
Geoffrey seems a bit too 60s for me, but I'm partial to the name because my dad is a
Jeffrey. I think that it has a nice sound but it was was too overused.
