[name_f]My[/name_f] first thought reading the title was that [name_f]Magdalena[/name_f] and [name_f]Evangeline[/name_f] would make a great sibset. They’re both elaborate names with direct ties to Christianity, though you don’t necessarily have to be [name_m]Christian[/name_m] to use them.
[name_f][/name_f]Seraphine/Seraphina is gorgeous and I really like potential nickname Saffy, but I think [name_f]Seraphine[/name_f] is a bit too close to [name_f]Evangeline[/name_f] for siblings. [name_f]Magdalena[/name_f], [name_f]Evangeline[/name_f], and [name_f]Seraphina[/name_f] could work, though. I even like how their endings all echo each other without being exactly matchy.
[name_f][/name_f][name_f]Sylvie[/name_f] feels like a very different energy. Shorter and sprightlier. I do really love [name_f]Sylvie[/name_f], though I worry she’s getting a bit trendy. Still you can’t beat a name that means “forest” and that silvery sound is so sweet.
