I've never been in the "placenames are down market" camp. And I've always had a particular fondness for the name
Geneva.
My only hesitation with
Geneva is that I hope it doesn't cause people to mispronounce
Ginevra as "ji-NEEV-ra," if you know what I mean.
But apart from that, I think
Geneva is a lovely name. Both
Ginny and
Neva work nicely as nns. Do you have any mns in mind for
Geneva?
