I think many two syllable names ending in a could work, a la [name_m]Jonah[/name_m] and [name_m]Noah[/name_m] [name_f][/name_f]- see [name_f]Kyra[/name_f], [name_f]Jessa[/name_f], [name_f]Nora[/name_f], [name_f]Willa[/name_f]. [name_f]Alma[/name_f] is already considered a masculine name in Mormon culture, since he’s a male figure in the Book of Mormon.
[name_f][/name_f][name_f]Heather[/name_f] [name_f][/name_f]- Similar to [name_m]Heath[/name_m], a bit tied to the 80s on a girl, but could be fresh on a boy. Amber’s another good one, a la [name_m]Jasper[/name_m].
[name_f][/name_f][name_f]Waverly[/name_f] [name_f][/name_f]- I could see [name_m]Wave[/name_m] really working for a boy.
[name_f][/name_f][name_f]Gwen[/name_f] [name_f][/name_f]- Feels similar to [name_f]Quinn[/name_f] and [name_m]Morgan[/name_m].
[name_f][/name_f][name_f]Grace[/name_f] [name_f][/name_f]- Similar to Grayson/Gray/Ace. If I heard this name with no prior associations, I’d probably assume it was masc based on the sound.
[name_f][/name_f][name_f]Elly[/name_f] [name_f][/name_f]- I admit I love [name_f]Elly[/name_f] on a boy and have for years. There’s something so playful and bright there. It could be short for [name_m]Elijah[/name_m] or [name_m]Elliott[/name_m], but would work as a standalone too. Side note: if Elijah/Elias is masculine, why not Eliza/Elise?
