Thank you all so much! I like a lot of your suggestions. My current list is:
Rosalie, Cecilia, Josette (Josie)Rosalie, Cecilia, Dorothea (Dotty, Thea, Dory)Rosalie, Cecilia, Eloise (Elsie)Rosalie, Cecilia, Marjorie (Jorie, Rory)Rosalie, Cecilia, Eloisa (Elsie)Rosalie, Cecilia, Aurora (Rory)Rosalie, Cecilia, Josephine (Josie)Rosalie, Cecilia, Persephone (Seffie, Percy)Rosalie, Cecilia, Lydia
Love Ophelia but I think it's too rhymey with Cecilia. Hermione I also really like but I don't think it'll carry well in the states as it's only known for Harry Potter there. Love Lucia but I think it shares too many sounds with Cecilia? I would pronounce it Loo-see-ah, but the pronunciation differences is another thing that would keep me away (I know I'm being fussy).
I like Aurelie and Aurelia more than Aurora, but Aurelie/orally puts me off, and Aurelia is too rhymey with Cecilia. I think I like both Persephone and Aurora more in theory than in practice.
Thoughts on Josiane?
I'm even just thinking Rosalie, Cecilia, and Josie at the point but it does seem a mismatch. Probably going to end up going with Eloise/Elsie, but I just really love Josie. I also can't get past Dorothea and Majorie, I really love them both. So the shortlist I suppose would be this:
Rosalie, Cecilia, Josette (Josie)
Rosalie, Cecilia, Dorothea (Dotty, Thea, Dory)
Rosalie, Cecilia, Eloise (Elsie)
Rosalie, Cecilia, Marjorie (Jorie, Rory)
Have just come across Dolly for Dahlia which I also like so much! Why are there so many gorgeous names in the world.
