Georgiana is not entirely unattractive, but it's a bit too long and drawn-out for me, and reminds me of languishing wimpy heroines.
Georgina is more fun and energetic - makes me think of Swinging Sixties girls with boots and big hair, à la
Georgy Girl.
Georgia is okay, but not something I'd use, because my dad loves singing '
Georgia On My Mind' and would drive her insane with it.
George is just the best name ever. I want to call everyone and everything
George.
