Some nice french female first names that,in my (french) opinion, sounds good in english:
- Amandine (from latin: kind)
- Mathilde (from 2 german words: force and fight)
- Elodie (from 2 german words: stranger and wealth.) Would be fun for a character who dies quick (you know, "Hello! / Die....". Oh well, Nevermind)
All in all you'd better finish the script first then find final names that fit the characters well.
