I like [name_f]Estelle[/name_f] [name_m]Valentine[/name_m]! I don’t think it’s too cutesy/playful (and I tend to dislike a lot of cutesy names that are widely loved on NB).
I really like [name_f]Estelle[/name_f] [name_f]Evangeline[/name_f] from your husbands likes. One of the first names that came to mind was [name_f]Estelle[/name_f] [name_f]Anastasia[/name_f] for the romantic and elegant vibe, but I don’t think it’s very [name_m]French[/name_m].
What about:
