[name]Jane[/name] [name]Evangeline[/name] ([name]Evie[/name], bc we already have two [name]Janes[/name] in the family)
[name]Jocelyn[/name] [name]Rebecca[/name] (the only drawback is that her monogram would be jAr - nn [name]Joss[/name] sounds too much like [name]Josh[/name], but [name]Jocelyn[/name] feels heavy for a little girl)
[name]Raina[/name] [name]Eleanor[/name] ([name]Rae[/name] or [name]Lena[/name] or no nickname at all)
for another boy, I’m leaning toward [name]Will[/name].
I vote for [name]Jane[/name] [name]Evangeline[/name]…it’s a beautiful classic name and I like the nn [name]Evie[/name]. [name]Evangeline[/name] [name]Jane[/name] would be great too!
What pronunciation are you using: Evange-LEEN, Evange-[name]LINE[/name], e-[name]VAN[/name]-gelinn? Because some of those work better with [name]Jane[/name] than others. 
I like [name]Raina[/name] [name]Eleanor[/name]
I would have to go with [name]Jane[/name] [name]Evangeline[/name], its a classic name, so elegant and simple and a wonderful sister to [name]Charlie[/name].
[name]Jane[/name] [name]Evangeline[/name] is quite lovely. Is there any specific reason why you have [name]Jane[/name] in front when you intend to use [name]Evie[/name]?
[name]Jocelyn[/name] is a masculine name to me, and so I struggle to picture it on a girl - perhaps [name]Josephine[/name], [name]Josepha[/name], [name]Josette[/name], [name]Josiane[/name] or possibly Jocosa would appeal as a long form of [name]Joss[/name], or use another nickname eg [name]Josie[/name], [name]Jo[/name], [name]Posy[/name], Sephy for [name]Josephine[/name], [name]Jock[/name] for Jocosa. [name]Rebecca[/name] is a great middle name.
[name]Raina[/name] is alright - I very much see 'rain with an ‘a’ and prefer the Bulgarian name [name]Rayna[/name] for that sound. [name]Eleanor[/name] is a fantastic name, though I wouldn’t place two ‘-a’ sound ending names together - it’s a little repetitive.
To mix things up a bit - I like [name]Jane[/name] [name]Eleanor[/name], [name]Rebecca[/name] [name]Evangeline[/name], [name]Evangeline[/name] [name]Jane[/name] and [name]Eleanor[/name] [name]Josephine[/name]/[name]Jocelyn[/name].
I like [name]Jane[/name] [name]Evangeline[/name] but also like the way it sounds when you switch them, [name]Evangeline[/name] [name]Jane[/name]. [name]Just[/name] to throw an idea out, I knew an [name]Evangelina[/name] and she went by [name]Vangie[/name]. Very unusual, don’t know if is your style, but another nn option is always good!
I like [name]Jane[/name] [name]Evangeline[/name] best. It’s beautifully classic, and it honors a family member while offering a fresh young nickname. It has my vote
I like [name]Evangeline[/name] [name]Jane[/name]
