G@briel, Im0gen,…
[name_f]Annika[/name_f] and [name_f]Caitriona[/name_f]
[name_f]Annika[/name_f] and [name_f]Katerina[/name_f]
[name_f]Annika[/name_f] and [name_f]Margot[/name_f]
[name_f]Annika[/name_f] and [name_f]Elise[/name_f] / [name_f]Eliza[/name_f]
[name_f]Annika[/name_f] and [name_f]Elizabeth[/name_f]
[name_f]Annika[/name_f] and [name_f]Audrey[/name_f]
[name_f]Annika[/name_f] and [name_f]Lilia[/name_f]
I like [name_f]Zoe[/name_f] and [name_f]Chloe[/name_f] a lot with [name_m]Gabriel[/name_m] and [name_f]Imogen[/name_f] (but not together)
[name_f]Zoe[/name_f] [name_f]Florence[/name_f] & [name_f]Mollie[/name_f] [name_u]Wren[/name_u] (my fave 
)
[name_f]Zoe[/name_f] [name_f]Katherine[/name_f] & [name_u]Wren[/name_u] [name_f]Margaret[/name_f]
[name_f]Zoe[/name_f] [name_f]Isabel[/name_f] & [name_f]Katherine[/name_f] [name_f]Emma[/name_f] ([name_u]Kit[/name_u])
[name_f]Chloe[/name_f] [name_f]Isabel[/name_f] & [name_f]Lena[/name_f] [name_f]Genevieve[/name_f]
[name_f]Chloe[/name_f] [name_f]Margaret[/name_f] & [name_f]Genevieve[/name_f] [name_f]Katherine[/name_f] ([name_f]Evie[/name_f])
[name_f]Chloe[/name_f] [name_f]Anna[/name_f] & [name_f]Katherine[/name_f] [name_f]Lilia[/name_f] (maybe too matchy with a C last name though)
[name_f]Anna[/name_f] [name_f]Florence[/name_f] & [name_f]Katherine[/name_f] [name_f]Isabel[/name_f] ([name_u]Kit[/name_u])
[name_f]Audrey[/name_f] [name_f]Anna[/name_f] & [name_f]Lena[/name_f] [name_f]Genevieve[/name_f]
Oops just saw your updated list. [name_f]My[/name_f] favorites are:
[name_u]Wren[/name_u] [name_f]Eloise[/name_f] & [name_f]Lucy[/name_f] [name_f]Florence[/name_f]
[name_f]Eloise[/name_f] [name_u]June[/name_u] & [name_f]Sophie[/name_f] [name_u]Wren[/name_u]
To my ear [name_f]Isabel[/name_f] is a little too close to [name_f]Imogen[/name_f] for sisters.
[name_f]Emma[/name_f] [name_f]Margaret[/name_f]
[name_f]Emma[/name_f] [name_f]Katherine[/name_f]
Loving your updated list! For pairs, maybe:
[name_f]Sophie[/name_f] [name_u]Wren[/name_u] and [name_f]Audrey[/name_f] [name_f]Clara[/name_f]
[name_f]Eloise[/name_f] “[name_f]Elle[/name_f]” [name_u]June[/name_u] and [name_f]Lucy[/name_f] [name_f]Florence[/name_f]
[name_f]Ada[/name_f] [name_f]Katherine[/name_f] and [name_f]Lucy[/name_f] [name_f]Florence[/name_f]
[name_f]Margaret[/name_f] “[name_f]Mollie[/name_f]” [name_f]May[/name_f] and [name_f]Elizabeth[/name_f] “[name_f]Beth[/name_f]” [name_u]Louise[/name_u] (not sure if nicknames are still on the table!)
I have to agree with @sarah1800 that [name_f]Isabel[/name_f] and [name_f]Imogen[/name_f] are a little closer than I would ideally like for sisters; I don’t think it has to be a dealbreaker, but if you’re looking for a way to narrow things down, that could be one!
[name_f]Zoe[/name_f] [name_f]Katherine[/name_f] and [name_u]Noa[/name_u] [name_f]Margaret[/name_f]
[name_u]Wren[/name_u] [name_f]Isabel[/name_f] and [name_u]Sloane[/name_u] [name_f]Florence[/name_f]

[name_f]Vada[/name_f] [name_f]Florence[/name_f] and [name_f]Lena[/name_f] [name_f]Katherine[/name_f]
[name_f]Margaret[/name_f] [name_f]Ava[/name_f] and [name_f]Genevieve[/name_f] [name_f]Lena[/name_f] “[name_f]Margo[/name_f] and [name_f]Evie[/name_f]”
I like the following combos best:
[name_f]Anna[/name_f] & [name_f]Lucy[/name_f]
[name_f]Anna[/name_f] & [name_f]Sophie[/name_f]
[name_f]Sophie[/name_f] & [name_f]Lucy[/name_f]
[name_f]Katherine[/name_f] & [name_f]Margaret[/name_f] ([name_f]Kitty[/name_f] & [name_f]Margot[/name_f])
[name_f]Felicity[/name_f] & [name_f]Annabel[/name_f]
[name_f]Felicity[/name_f] & [name_f]Isabel[/name_f]
[name_f]Isabel[/name_f] & [name_f]Cecelia[/name_f]
[name_f]Annabel[/name_f] & [name_f]Cecelia[/name_f]
Good luck and have great fun choosing! x
Congratulations on your twins and welcome to Nameberry! Ok, from your new longish short list…
I would cut:
[name_f]Annika[/name_f] [name_u]Sloane[/name_u] - This name just feels a bit harsh and less feminine than all your other options.
[name_f]Anna[/name_f] [name_u]Wren[/name_u] - Too short.
[name_f]Isabel[/name_f] - I think [name_f]Imogen[/name_f] and [name_f]Isabel[/name_f] are too close, which is unfortunate, since otherwise it would be a great fit for you. I also don’t love any of the suggested middles.
[name_f]Audrey[/name_f] [name_u]Anne[/name_u]-[name_u]Marie[/name_u] - I’m pretty adamantly against a hyphenated middle. It seems like more of a hassle (in paperwork, etc) than it’s worth.
[name_u]Wren[/name_u] [name_f]Eloise[/name_f] - I love [name_u]Wren[/name_u], but not sure it’s a good fit with your other children and the other contenders here. Would be a sweet middle or nickname.
[name_f]My[/name_f] favorites of the remaining options:
[name_f]Katherine[/name_f] [name_f]Emma[/name_f] - LOVE the idea of a little [name_u]Kit[/name_u], and [name_f]Emma[/name_f] is a sweet and unexpected middle.
[name_f]Margaret[/name_f] [name_f]Sophie[/name_f]/[name_f]Margaret[/name_f] [name_f]Isabel[/name_f] - You have so many nickname possibilities here, and I like that these are both classic without being boring.
[name_f]Ada[/name_f] [name_f]Katherine[/name_f] - [name_m]Gabriel[/name_m], [name_f]Imogen[/name_f] and [name_f]Ada[/name_f] is perfection. This combo also reminds me of [name_f]Ada[/name_f] [name_u]Lovelace[/name_u] and [name_f]Katherine[/name_f] [name_m]Johnson[/name_m] – two pioneering women in STEM!
[name_f]Lucy[/name_f] [name_f]Florence[/name_f] - I’m a sucker for [name_f]Lucy[/name_f]. It’s just the sweetest little name. Would be so nice as a twin to [name_f]Beth[/name_f].
[name_f]Eloise[/name_f] [name_u]June[/name_u] - This one is a bit more unexpected than your others, but I think it’s a great style match and [name_u]June[/name_u] is my favorite.
[name_u]Noa[/name_u] and [name_f]Emma[/name_f] are a great pair!
I love [name_f]Elizabeth[/name_f] ([name_f]Beth[/name_f]) and [name_f]Emma[/name_f]. I also like the idea of using [name_f]Katerina[/name_f] instead of [name_f]Katherine[/name_f] with the nn [name_u]Kit[/name_u] or [name_f]Kitty[/name_f]. Other nn could be [name_f]Rina[/name_f] or [name_f]Kat[/name_f].
Since you can’t use [name_f]Eleanor[/name_f], have you considered something similar such as [name_f]Elena[/name_f] or [name_f]Nora[/name_f] (both can be short for [name_f]Eleanor[/name_f] or stand on their own)?
Of your family names I really like [name_f]Margaret[/name_f] and [name_f]Katherine[/name_f]- lots of great nickname potential. [name_f]Margo[/name_f], [name_f]Mollie[/name_f], and [name_f]Greta[/name_f], and [name_f]Meg[/name_f] woould be great for [name_f]Margaret[/name_f]. I love Ryn, Rinnie, [name_u]Kit[/name_u], [name_f]Kitty[/name_f], and [name_u]Wren[/name_u] as nicknames for [name_f]Katherine[/name_f]! You could also use a variation like [name_f]Katrina[/name_f], [name_f]Katia[/name_f]/[name_f]Katya[/name_f], [name_f]Katerina[/name_f], and [name_f]Kathleen[/name_f].
For [name_f]Emma[/name_f] and [name_f]Ava[/name_f] they could be nicknames for a longer less common name. [name_f]Emmeline[/name_f] and [name_f]Emilia[/name_f] or [name_f]Avis[/name_f], [name_f]Aviana[/name_f], and [name_f]Aviva[/name_f], perhaps?
I really do like [name_u]Noa[/name_u] for girls. I like the double name [name_u]Noa[/name_u]-[name_u]Jo[/name_u].
[name_f]Genevieve[/name_f] is beautiful! One of my favorites. [name_u]Sloane[/name_u] is spunky and androgynous- love it. [name_f]Lilia[/name_f] is also very pretty.
Some combo suggestions based on your names:
[name_f]Genevieve[/name_f] [name_f]Ann[/name_f] “[name_f]Evie[/name_f]” and [name_f]Emmeline[/name_f] [name_f]Isabel[/name_f] “[name_f]Emma[/name_f]”
[name_u]Sloane[/name_u] [name_f]Beatrix[/name_f] and [name_u]Noa[/name_u] [name_f]Florence[/name_f]
[name_f]Katherine[/name_f] [name_u]Sloane[/name_u] “[name_u]Kit[/name_u]” and [name_f]Elizabeth[/name_f] [name_f]Margaret[/name_f] “[name_f]Beth[/name_f]”
[name_f]Margaret[/name_f] [name_u]Noa[/name_u] “[name_f]Margo[/name_f]” and [name_f]Lilia[/name_f] [name_f]Genevieve[/name_f]
[name_f]Genevieve[/name_f] [name_f]Katherine[/name_f] “[name_f]Evie[/name_f]” and [name_f]Margaret[/name_f] [name_f]Vada[/name_f] “[name_f]Margo[/name_f]”
[name_f]Emmeline[/name_f] [name_f]Isabel[/name_f] “[name_f]Emma[/name_f]” and [name_f]Margaret[/name_f] [name_u]Noa[/name_u] “[name_f]Mollie[/name_f]”
Some suggestions based on your style:
[name_f]Evangeline[/name_f]
[name_f]Josephine[/name_f]
[name_f]Beatrix[/name_f]
[name_f]Vera[/name_f]
[name_f]Cecily[/name_f]
[name_f]Teresa[/name_f]
[name_f]Charlotte[/name_f]
[name_f]Adelaide[/name_f]
[name_f]Phoebe[/name_f]
[name_f]Matilda[/name_f]
If you’re getting “[name_u]Wren[/name_u]” from [name_f]Katherine[/name_f] through the rin part, you might also be able to get “(W)ren” from [name_f]Flo[/name_f]rence. I could be stretching it though!
[name_f]My[/name_f] favourite combo is [name_f]Genevieve[/name_f] “[name_f]Eve[/name_f]” and [name_f]Florence[/name_f] “[name_u]Ren[/name_u].” Both are timeless and elegant names!
Exciting update! While there’s still still a chance we could change our minds, but for the most part, we think we’ve landed on two we really love!
[name_f]Margaret[/name_f] [name_f]Isabel[/name_f] (called either [name_f]Mollie[/name_f], [name_u]Kit[/name_u], or [name_f]Margo[/name_f], depending on what fits best!) and [name_f]Eloise[/name_f] [name_u]June[/name_u] (likely called [name_f]Elle[/name_f]!)
I was a bit sad to let some favorites go, especially [name_f]Genevieve[/name_f], [name_f]Anna[/name_f], [name_f]Audrey[/name_f], and [name_f]Katherine[/name_f], I’m head over heels for the names we picked. Thank you all so much for all your help!
Gorgeous names!!! Congratulations on really lovely choices.
[name_f]Margaret[/name_f] & [name_f]Eloise[/name_f], [name_u]Kit[/name_u] & [name_f]Elle[/name_f]. Swoon!!
What a beautiful list!! Congratulations for your decision! [name_f]Margaret[/name_f] [name_f]Isabel[/name_f] and [name_f]Eloise[/name_f] [name_u]June[/name_u] are stunning names for twins. 
These were my favorite names from your list:
[name_f]Margaret[/name_f] [name_f]May[/name_f]
[name_f]Margaret[/name_f] [name_f]Inez[/name_f]
[name_f]Margaret[/name_f] [name_f]Isabel[/name_f]
[name_f]Lilia[/name_f] [name_f]Katherine[/name_f]
[name_f]Sophie[/name_f] [name_u]Wren[/name_u]
[name_f]Ada[/name_f] [name_f]Katherine[/name_f]
[name_f]Eloise[/name_f] [name_u]June[/name_u]
[name_f]Lucy[/name_f] [name_f]Florence[/name_f]
[name_f]Elizabeth[/name_f] [name_u]Louise[/name_u]
Since you already have a girl with the initial I, I love that you kept [name_f]Isabel[/name_f] as a middle name. With [name_m]Gabriel[/name_m] and [name_f]Imogen[/name_f], I also loved [name_f]Ada[/name_f] and [name_f]Lucy[/name_f].
Good luck! 
[name_f]Florence[/name_f] and [name_f]Katerina[/name_f] (to honor [name_f]Katherine[/name_f])
[name_f]Marguerite[/name_f] (to honor [name_f]Margaret[/name_f]) and [name_f]Lena[/name_f]
[name_f]Lilia[/name_f] and [name_f]Elsbeth[/name_f] (another way to get [name_f]Beth[/name_f] from a fellow [name_m]Little[/name_m] Women fanatic :))
[name_f]Beatrix[/name_f] (similar to [name_f]Beatrice[/name_f]) and [name_f]Tessa[/name_f] (similar to [name_f]Tess[/name_f])=> [name_f]Trixie[/name_f] and [name_f]Tess[/name_f]
[name_f]Annalisa[/name_f] (similar to [name_f]Anna[/name_f] but not as common) and [name_f]Florence[/name_f]=> [name_f]Anna[/name_f] and [name_f]Flo[/name_f]
[name_f]Elnora[/name_f] (similar to [name_f]Eleanor[/name_f]) and [name_f]Carolina[/name_f] (similar to [name_f]Caroline[/name_f])
Congratulations!!! Twin girls is so fun!!
I love [name_f]Marguerite[/name_f], but it’s actually a family member’s name already! Thankfully, she goes by [name_f]Maggie[/name_f] exclusively, which is why I’m able to use [name_f]Margaret[/name_f] without a hitch!
Also, [name_f]Trixie[/name_f] and [name_f]Tess[/name_f] are absolutely precious - swoon!
We have similar style!
What about [name_f]Margaret[/name_f] and Madalena/[name_f]Magdalena[/name_f]? Nicknames [name_f]Margo[/name_f] or [name_u]Kit[/name_u] and [name_f]Lena[/name_f]? I agree [name_u]Kit[/name_u] is adorable.
We landed on [name_f]Margaret[/name_f] [name_f]Isabel[/name_f] and [name_f]Eloise[/name_f] [name_u]June[/name_u] ([name_u]Kit[/name_u] & [name_f]Elle[/name_f]!) last night, but Iove Madalena! I just couldn’t use it because my name is [name_f]Madeline[/name_f] and it’s just too close for me!
Congratulations!!! [name_f]Margaret[/name_f] [name_f]Isabel[/name_f] and [name_f]Eloise[/name_f] [name_u]June[/name_u] are gorgeous and [name_u]Kit[/name_u] and [name_f]Elle[/name_f] are absolutely precious!!
