Or at least most plausible…
[name_f]Josephine[/name_f]: [name_f]Poppy[/name_f], [name_f]Effie[/name_f] or [name_f]Sophie[/name_f]? Any I’ve missed? I don’t like [name_f]Posy[/name_f] and don’t want to use [name_u]Josie[/name_u].
[name_f]Charlotte[/name_f]: [name_f]Lola[/name_f], [name_u]Arly[/name_u]/[name_u]Arlie[/name_u]? Any more?
[name_f]Ophelia[/name_f]: [name_f]Fia[/name_f] (although I prefer this for [name_f]Serafina[/name_f] I think?), [name_f]Pia[/name_f] (not sure) and Ophie (I feel like this would become too cute too quickly). Suggestions?
[name_f]Clementine[/name_f]: Does [name_f]Nettie[/name_f] work is is that too much of a stretch? What about [name_f]Cleo[/name_f]? Which do you prefer?
[name_u]Waverly[/name_u]/[name_f]Waverley[/name_f]: First of all, which spelling do you prefer, with or without the e? [name_f]Avie[/name_f]? I can’t think of anything else.
For [name_f]Josephine[/name_f] I really like [name_f]Poppy[/name_f]!! Super sweet. What about [name_u]Jo[/name_u], [name_u]Jojo[/name_u], [name_u]Joey[/name_u]?
I like [name_f]Lola[/name_f] for [name_f]Charlotte[/name_f], have you considered [name_f]Lottie[/name_f]? I love [name_f]Lottie[/name_f]!
[name_f]Ophelia[/name_f] is a tough one, is Filly too strange?
I think [name_f]Nettie[/name_f] sounds alright! [name_f]Cleo[/name_f] is cute too 
What about [name_f]Minnie[/name_f]?
I prefer the [name_u]Waverly[/name_u] spelling, and like [name_f]Ophelia[/name_f], this one is a bit of tough one! Perhaps V or [name_f]Vivi[/name_f]?
[name_f]Hope[/name_f] this helps!
[name_f]Josephine[/name_f]: I like [name_f]Poppy[/name_f] from these choices. I also like Phi (pronounced fee).
[name_f]Charlotte[/name_f]: [name_f]Lola[/name_f] or [name_f]Lottie[/name_f]!
[name_f]Ophelia[/name_f]: [name_f]Pia[/name_f] is cute. Phi/Phe again for this one. Ophie sounds oaf-y :\
[name_f]Clementine[/name_f]: Sure, [name_f]Nettie[/name_f] or [name_f]Cleo[/name_f] work. Probably prefer [name_f]Nettie[/name_f], but mostly [name_f]Clementine[/name_f] in full.
[name_u]Waverly[/name_u]/[name_f]Waverley[/name_f]: [name_f]Avie[/name_f] or [name_f]Ava[/name_f]. I’m not sure about spelling but I guess [name_u]Waverly[/name_u].
[name_f]Josephine[/name_f]: I like [name_f]Effie[/name_f] best, but Seffie/Sephy was the first thing that came into my mind with this name!
[name_f]Charlotte[/name_f]: I like [name_u]Arlie[/name_u]! I’ve never heard that before. [name_f]Lottie[/name_f] & [name_u]Charlie[/name_u] are the most obvious ones. Maybe Oti? That might be a bit of a stretch though.
[name_f]Ophelia[/name_f]: I agree with @cactusgram on this one. [name_f]Pia[/name_f] is sweet - There’s also Fi and [name_f]Lia[/name_f]
[name_f]Clementine[/name_f]: [name_f]Cleo[/name_f] is more plausible, but I love [name_f]Nettie[/name_f] - you could definitely make that work.
[name_u]Waverly[/name_u] (I prefer that spelling): [name_f]Ava[/name_f]/[name_f]Avie[/name_f]/[name_f]Lia[/name_f]
