I use Aubergine and Eggplant interchangably, so it is
really weird to me.
It certainly does sound very namey, and I'm a sucker for names with that beautiful au and names ending in ~ine so I think I would like it if it weren't, like, a vegetable.
Can I suggest
Wilhelmine,
Jessamine,
Albertine,
Eglantine! (I love
Eglantine. In particular
Vera Eglantine)
Aubert,
Aurelia?
