Ashe: I like it, but I prefer
Ash for a boy or
Asha for a girl.
Constance: I like this, especially as a middle name.
Connie is cute although it feels older to me.
Dorothea: It's got a quirky vintage feel, I also prefer this one as a middle name but I do like all the nickname options when it's a first name.
Juno: I prefer
Minerva but I do think
Juno is more manageable since it's short and snappy and has nicknames like
June and Junie. It's a good mix between ancient mythology and a more modern sound.
Liliana: It's cute and pretty. I feel like it's overused but I don't actually know any so maybe it's not.
Lili,
Lily,
Liana,
Lilia,
Ana,
Lana, Lil,
Lia... lots of nicknames.
Maribelle: It's alright. I don't think this is one of the more mature ones, I think
Constance and
Dorothea are the most mature. The only reason I'm "meh" on this name is that I prefer Mirabel and
Mirabelle.
Rowan: I would use this one!
Yumi: I like it, I think of
Yumi and the Nightmare Painter.
