I'm writing a story and want to name a character Imogen, but that name also belongs to someone I know and isn't the type of person I'd like to name this character after. I've been looking for some replacement names that have a similar-enough vibe to what I want, and this is the list I've come up with:
Indigo
Idalia
Celine
Cosette
Idella
Alison
Amethyst
Eloise
Emilia
Eulalia
Ophelia
Any ideas on which one fits best? Or do you have other names that have a similar feel? There's a couple names that could fit, like Isabelle, that I chose against including on the list for the same reason - I know someone with the name and don't want to name a character after them.
