I haven't seen the movie, but I've heard that
Neil Gaiman wrote Coraline as a typo for
Caroline, and liked the look of it. Does that mean that Coraline rhymes with
Caroline? Or is it Coraleen?
It makes me think of a textile, perhaps dress material or curtaining. I far prefer either
Caroline or
Coralie.
Georgiana is inconveniently long, however it's pronounced. Lots of people seem to say it like jorJANEa, which makes no sense.
Georgina is much less fussy; I could see
Georgina Coralie, or
Coralie Georgina, or the same but with
Caroline instead of
Coralie.
Not much help, I'm afraid!
