These are all completely theoretical combos, I just wanted to know what you guys thought!
[name]Anya[/name] [name]Vida[/name]
[name]Susannah[/name] [name]Lily[/name] - Too repetitive? ([name]Susannah[/name] means lily)
[name]Petra[/name] [name]Sofia[/name]
[name]Andromeda[/name] [name]Elena[/name] - The middle name is kind of tentative
[name]December[/name] [name]Skye[/name] - Too hippy? Too weird?
[name]Alice[/name] [name]Frances[/name]
[name]Helena[/name] [name]Cordelia[/name]
[name]Natalia[/name] [name]Elizabeth[/name]
[name]Zoe[/name] [name]Tatiana[/name]
Can’t wait for opinions! TTFN! 
[name]Anya[/name] [name]Vida[/name] - I don’t like this, [name]Anya[/name] is quite pretty but I think [name]Vida[/name] sounds strange, sorry 
[name]Susannah[/name] [name]Lily[/name] - I love both of these names but yes think they are too repetitive together.
[name]Petra[/name] [name]Sofia[/name] - gorgeous!
[name]Andromeda[/name] [name]Elena[/name] - This is ok, I think [name]Andromeda[/name] is a bit too much name for a little girl though.
[name]December[/name] [name]Skye[/name] - For me this is too hippy and too weird, sorry!
[name]Alice[/name] [name]Frances[/name] -[name]LOVE[/name] [name]Alice[/name], dislike [name]Frances[/name]. Together it sounds a bit matchy - the c sounds in both names are too similar.
[name]Helena[/name] [name]Cordelia[/name] - gorgeous!
[name]Natalia[/name] [name]Elizabeth[/name] - I don’t like [name]Natalia[/name], but these sound quite nice together.
[name]Zoe[/name] [name]Tatiana[/name] - I really don’t like [name]Zoe[/name], like [name]Tatiana[/name] though.
[name]Hope[/name] I helped!
[name]Anya[/name] [name]Vida[/name] - I see [name]Anya[/name]'s appeal, but I prefer other [name]Anna[/name] names, personally. [name]Vida[/name]/[name]Vita[/name]/[name]Avita[/name]/Avida/etc. are too Hollywood-esque for me right now. A few years ago I think there were five little Hollywood babies who had some form of [name]Vida[/name] or [name]Vita[/name] as either her FN or MN…
[name]Susannah[/name] [name]Lily[/name] - Too repetitive? ([name]Susannah[/name] means lily) - yeah, too repetitive for me. I do like both names, but I think it’s repetitive together.
[name]Petra[/name] [name]Sofia[/name] - love [name]Sofia[/name], but I’m not a huge fan of [name]Petra[/name], personally. I love the rhythm of this, though.
[name]Andromeda[/name] [name]Elena[/name] - The middle name is kind of tentative - [name]Andromeda[/name] [name]Elena[/name] is a lot of name, for me. I am growing to see the appeal of [name]Andromeda[/name]–it’s one of my sister’s favorites–but I don’t love it. I like [name]Elena[/name] [name]Andromeda[/name] a lot more, personally.
[name]December[/name] [name]Skye[/name] - Too hippy? Too weird? - yeah, too hippy for me. I’m not really a fan of the nns, either–[name]Ember[/name] or Decy seem like the only usable ones, and I’m not a fan. I like [name]Emmy[/name], but most people think that’s a stretch…
[name]Alice[/name] [name]Frances[/name] - [name]LOVE[/name] [name]Alice[/name]. [name]Frances[/name] pairs with it very nicely.
[name]Helena[/name] [name]Cordelia[/name] - [name]LOVE[/name] [name]Cordelia[/name]. I love [name]Helena[/name], too, but as [name]Hannah[/name] [name]Cordelia[/name] is a combo on my own list, this seems similar enough to be familiar, but different enough that it seems to be missing something. :*(
[name]Natalia[/name] [name]Elizabeth[/name] - eh. It’s okay. [name]Natalie[/name] is my sister, and if it weren’t for her, I probably wouldn’t give [name]Nat[/name]- names a second look.
[name]Zoe[/name] [name]Tatiana[/name] - I think [name]Zoe[/name] is pretty, and I like its meaning, but I prefer it as a MN. I’m not too fond of [name]Tatiana[/name], sorry.
[name]Alice[/name] is my favorite! I also like [name]Helena[/name] as a FN, though.
Good luck!
[name]Anya[/name] [name]Vida[/name] - rhythm is off I love [name]Anya[/name] though
[name]Susannah[/name] [name]Lily[/name] - I think its sweet
[name]Petra[/name] [name]Sofia[/name] - not a fan of either really
[name]Andromeda[/name] [name]Elena[/name] - I [name]LOVE[/name] [name]Elena[/name] but [name]Andromeda[/name] is way too much name [name]IMO[/name]
[name]December[/name] [name]Skye[/name] I think its nice I prefer [name]November[/name] to [name]December[/name] but to each their own
[name]Alice[/name] [name]Frances[/name] - the double “s” ending really throws off the name but I think [name]Frances[/name] is lovely
[name]Helena[/name] [name]Cordelia[/name] - the double “a” ending throws this off as well. What about [name]Alice[/name] [name]Cordelia[/name] and [name]Helena[/name] [name]Frances[/name] to break things up and keep all your names 
[name]Natalia[/name] [name]Elizabeth[/name] -very classic
[name]Zoe[/name] [name]Tatiana[/name] I think [name]Tatiana[/name] [name]Zoe[/name] would sound so much better
[name]Natalia[/name] [name]Elizabeth[/name]
[name]Zoe[/name] [name]Tatiana[/name]
are my favorite. I also love [name]Helena[/name], just not a fan of [name]Cordelia[/name]. [name]Anya[/name] is great, but not with [name]Vida[/name]… The name [name]December[/name] [name]Skye[/name] is intriguing. Andeomeda is too much.
[name]Anya[/name] [name]Vida[/name]: I like [name]Anya[/name]! Normally I like [name]Vida[/name] but for some reason this combo doesn’t work [name]IMO[/name].
[name]Susannah[/name] [name]Lily[/name]: Is it just repetitive because [name]Susannah[/name] means lily? Not at all! No one in real life will know the meaning of [name]Susannah[/name]. I think it’s perfectly fine, and I really like it.
[name]Petra[/name] [name]Sofia[/name]: Like them separately but not together. [name]Petra[/name] is a tricky name.
[name]Andromeda[/name] [name]Elena[/name]: [name]LOVE[/name]! Perfect!
[name]December[/name] [name]Skye[/name]: I REALLY like it, but it is a bit hippy-ish.
[name]Alice[/name] [name]Frances[/name]: [name]Don[/name]'t like, sorry. Not a fan of either.
[name]Helena[/name] [name]Cordelia[/name]: Same as [name]Alice[/name] [name]Frances[/name].
[name]Natalia[/name] [name]Elizabeth[/name]: Really, really like [name]Natalia[/name]! [name]Elizabeth[/name] is a bit plain though, it seems like a filler MN.
[name]Zoe[/name] [name]Tatiana[/name]: Nice but could be better
I love hippy and weird although I wouldn’t use [name]December[/name] [name]Skye[/name] as much as I love how it sounds. Actually, for a girl I recently thoughs of [name]Marlyn[/name] [name]Skye[/name]. [name]Reason[/name]? My dad’s name is [name]Mark[/name], Mom is [name]Lynn[/name]. My brother is [name]Scott[/name] and brother in law is [name]Kyle[/name]… So it kind of mixes everyone in!
[name]Anya[/name] [name]Vida[/name] - I feel like this has weird flow, and I’m not much a fan of [name]Vida[/name]. I like [name]Anya[/name]. I almost always like -ya names, but that might because I love the singer Kimya Dawson heheh
[name]Susannah[/name] [name]Lily[/name] - I dont think it’s too repetitive, I don’t think many people know the meaning of [name]Susannah[/name]. I like the flow, but I’m not really a fan of the name [name]Susannah[/name].
[name]Petra[/name] [name]Sofia[/name] - I don’t like the rhyming so much on names. It bothers me. I think it’s awkward if the third name doesn’t rhyme as well and too cutesy when it does. Especially when they have the same number of syllables.
[name]Andromeda[/name] [name]Elena[/name] - Again with the rhyming… But then I do like [name]Andromeda[/name]. I’d pick another greek name with it, but one a little less obvious. But then, I’m partial to greek names (my pseudonym ln is [name]Athene[/name]).
[name]December[/name] [name]Skye[/name] - I love this! It’s my favourite of your names. I think it sounds more hippie-like when said aloud rather than written down, but I don’t mind hippie names at all. My friend loves the name [name]Rainbow[/name] [name]Summer[/name] and I think it’s adorable as well.
[name]Alice[/name] [name]Frances[/name] - I like [name]Alice[/name], but I’ve always have had a deep rooted hatred of the name [name]Frances[/name] since just a little kid. It’s one of my least favourite names, sorry.
[name]Helena[/name] [name]Cordelia[/name] - Again with the rhyming! Although this one isn’t so bad as the others. I’m not much a fan of either of the names tho…
[name]Natalia[/name] [name]Elizabeth[/name] - I like [name]Natalia[/name]! I’ve met a couple of [name]Natalie[/name]s and I like this fresh new version. I don’t like [name]Elizabeth[/name] tho, I’d suggest maybe [name]Emma[/name].
[name]Zoe[/name] [name]Tatiana[/name] - I like this one! I think it has a really nice flow to it, and I think [name]Zoe[/name] is normal without being overused or old. This is all if you pronounce it like Zoh-ee. I don’t like it as Zoh.
