[name_f]Clementine[/name_f]: Having looked at the rest of your list, this name seems to bridge all of the facets of your naming style really well. It’s offbeat and whimsical, like [name_f]Cleo[/name_f], [name_f]Indie[/name_f], [name_f]Olive[/name_f], et. all, but also vintage and classic, like [name_f]Ramona[/name_f], [name_f]Matilda[/name_f], [name_f]Florence[/name_f] and [name_f]Millie[/name_f]. I personally really like it, especially because it has such a lovely meaning: “mild, merciful.”
[name_f]Cleo[/name_f]: If you have both [name_f]Clementine[/name_f] and [name_f]Cleo[/name_f] on your list, I’d just use [name_f]Clementine[/name_f] and go with [name_f]Cleo[/name_f] for short. That way you get two for one :). I like [name_f]Cleo[/name_f], but I’m more comfortable with it with a longer name to anchor it and make it age well (like [name_f]Clementine[/name_f]!)
[name_f]Indie[/name_f]: I like it as a nickname for [name_u]Indigo[/name_u], but on its own, it’s a little too on-the-nose for me, if you know what I mean?
[name_u]Juniper[/name_u]: Everything I said about [name_f]Clementine[/name_f] goes for [name_u]Juniper[/name_u], to some extent. It also has the added benefit of the nickname [name_f]Junie[/name_f], which feels a lot like [name_f]Indie[/name_f] and [name_f]Millie[/name_f]. I love how precocious the name [name_u]Juniper[/name_u] sounds. Not sure why it makes me picture a little genius.
[name_u]Wynter[/name_u]: I like [name_u]Winter[/name_u], especially as a middle name (which is odd, because I don’t like lowercase-w winter). But the y here ruins it a bit for me. Have you thought about [name_f]Elowen[/name_f]?
[name_f]Matilda[/name_f]: I like [name_f]Matilda[/name_f]. It’s sweet and gentle.
[name_f]Millie[/name_f]: Have you considered [name_f]Romilly[/name_f]? [name_f]Millie[/name_f] is sweet, but I’m not sure how I feel about it on its own.
[name_f]Olive[/name_f]: So sweet. But I wonder if it will age well? I think the name [name_f]Olive[/name_f] might be a bit too informal for some people at some point in their lives.
[name_f]Ramona[/name_f]: Depending on whether or not I’m thinking of [name_f]Ramona[/name_f] from the chapter books or Moaning [name_f]Myrtle[/name_f] (not sure why this ever comes to mind, given that there’s only one syllable in common, but it often does) I either like this name or find it sort of morose sounding.
[name_m]Romie[/name_m]: See [name_f]Millie[/name_f]! I have the exact same opinion about [name_m]Romie[/name_m].
[name_f]Calliope[/name_f]: I love how lively [name_f]Calliope[/name_f] is, although it feels like a name that can dominate the person. I can see this getting much more popular, now that [name_f]Penelope[/name_f] is such a common name and the people who probably gravitated to [name_f]Penelope[/name_f] pre-Kardashians might not gravitate to it as much anymore.
[name_u]Mars[/name_u]: Too out there for me, literally maybe as a nickname for [name_f]Amara[/name_f]?
[name_f]Florence[/name_f]: The meaning (“flourishing”) makes this name for me. I think I prefer it as a middle name, but it’s pretty and elegant.
[name_u]Wren[/name_u]: I like it as a middle name. As a first name, the sound is a bit bare for me.
In sum –*favorites are [name_f]Clementine[/name_f] and [name_u]Juniper[/name_u], least favorite is [name_u]Mars[/name_u]. I think the name [name_f]Romilly[/name_f] would work really well for you.
