Name help!

We are waiting to find out the sex of our baby until it's born and have picked a boys name but are torn on a girls name. We both love girl names that can be shortened to "male/adrogynous" names. I've always loved Charlotte with the nickname Charlie, but our baby was conceived while we were staying at an old plantation home called the Josephine, so we thought Josephine with the nickname Joey would also be adorable. Now we can not decide. Opinions?
