I think I would go with [name_u]Sascha[/name_u] [name_f]Grace[/name_f].
But I would also consider [name_f]Millie[/name_f] [name_f]Rosalie[/name_f], Mary-Beth, [name_f]Emilia[/name_f] [name_f]Madeleine[/name_f], [name_u]Campbell[/name_u] [name_f]Amelia[/name_f] and [name_f]Faye[/name_f] [name_f]Alice[/name_f].
[name_f]Nora[/name_f] [name_f]Stephanie[/name_f] is great! I love [name_f]Nora[/name_f], they sound good together and I love that they mean “a crown of light”.
I’d choose [name_f]Emilia[/name_f] [name_f]Madeleine[/name_f]. A little more popular than I’d like, but still lovely and classic— and these are both my favorite versions/spellings as well.
I don’t know if this counts but I’d chose [name_f]Amber[/name_f] [name_u]Rain[/name_u] and convert it to [name_u]Ember[/name_u] [name_u]Rayne[/name_u]. If not I’ll leave it as it is.
I sort of wish I could steal [name_u]Ember[/name_u] [name_u]Rayne[/name_u] and give her another middle.
[name_f]Iona[/name_f] [name_f]Lilli[/name_f] (though I personally would spell it as Lily), [name_f]Millie[/name_f] [name_f]Rosalie[/name_f] or [name_f]Faye[/name_f] [name_f]Alice[/name_f]
I might pick [name_f]Marceline[/name_f] [name_f]Rachel[/name_f]. I absolutely adore [name_f]Marceline[/name_f], and I’m quite fond of [name_f]Rachel[/name_f] for its Friends association and the meaning.
[name_f]My[/name_f] second choice would be [name_f]Mila[/name_f] [name_f]Ann[/name_f].
