There are some
Harry Potter connotations, but I think its one of the names that can work.
Ginevra on its own is very lovely, and not a lot people realise that its
Ginny Weasley's full name. In fact a lot of people confuse it and thinks its Ginerva. (Like
Minerva with a G, I made that mistake the first time too...)
Ginny as a nickname however, can really go either way. It's nice though!
If it wasn't a
Harry Potter name, I'd think about using it. I'm a die hard
Harry Potter fan, and all of my family and friends know it and would probably never let it go. Oh well, there's still always
Guinevere.
