I’d love to throw my support behind [name_f]Lucy[/name_f]. It seems really well balanced with your other girls [name_f][/name_f]- I like that it’s four letters, a la [name_f]Jane[/name_f], but the sound is longer and bouncy like [name_f]Marigold[/name_f]. The meaning light also feels gently [name_m]Christian[/name_m]. [name_f]Lucie[/name_f] as a spelling is good as well, though I prefer the more traditional [name_f]Lucy[/name_f].
[name_f][/name_f]I think [name_f]Grace[/name_f] also works. Yes, it is one syllable and has a long history like [name_f]Jane[/name_f], but it is a word name like [name_f]Marigold[/name_f] and both have that strong g sound, and all three share the [name_m]Christian[/name_m] overtones and pleasantly similar vowel sounds. [name_f]Marigold[/name_f], [name_f]Jane[/name_f], and [name_f]Grace[/name_f] are an adorable set.
[name_f][/name_f]Some other ideas:
[name_f][/name_f][name_f]Elise[/name_f] [name_f][/name_f]- means “pledged to God” and I think has the ties to [name_f]Jane[/name_f] while not being so trim / having a Marigold-like-rhythm. [name_f]Eliza[/name_f] or even [name_f]Elspeth[/name_f] might also appeal.
[name_f][/name_f][name_f]Susanna[/name_f] [name_f][/name_f]- means lily and has some apocryphal bible ties as well as sounding like [name_f]Hosanna[/name_f]. Might be too floral, but isn’t as obvious as [name_f]Flora[/name_f] and has the same classic pedigree as [name_f]Jane[/name_f].
[name_f][/name_f][name_f]Lydia[/name_f] [name_f][/name_f]- an early biblical [name_m]Christian[/name_m] with a fun, lilting name.
[name_f][/name_f][name_f]Beatrix[/name_f] or [name_f]Beatrice[/name_f] [name_f][/name_f]- means “blessed” or “she who brings happiness”. [name_f]Beatrix[/name_f] to me leans slightly quirky in the same way [name_f]Marigold[/name_f] does, but both have long literary histories.
[name_f][/name_f][name_f]Fenna[/name_f] [name_f][/name_f]- a bit of an outlier, but means “peace” in [name_m]Dutch[/name_m] and Frisian and is a lovely soft name that to me sounds a bit like a non-Frances [name_f]Frances[/name_f].
[name_f][/name_f][name_f]Hope[/name_f] this sparks something for you. Congrats on your upcoming little one!
