I have been liking the name
Ravenna for a while, but I don't know if I'd actually use it on a child. For me, the sound seems to fall with
Vanessa or
Rowena, both names I also like.
I always love a good poetry connection!! But then again, I also love the sound of Vienna, but this is another name I would be cautious of using for a baby. Naming after cities is a dubious thing, imo.
