I envision this name fitting a beautiful maiden stepping out of an obscure Arthurian legend… or someone who enjoys playing such roles at the local Renaissance fair, haha. 
I do prefer [name_f]Guinevere[/name] and [name_f]Lilivere[/name], but Annavere has charm—she is interesting and distinctive! [name_f]Navie[/name] is not my cup of tea however, I would probably use [name_f]Annie[/name] or [name_f]Nan[/name].
