These got my vote:
[name]Catherine[/name] [name]Wisteria[/name] - [name]Lovely[/name], absolutely lovely! I love [name]Wisteria[/name] and it makes a great middle name! A pleasant surprise.
[name]Catherine[/name] [name]Verity[/name] - I prefer [name]Verity[/name] over a lot of the other middle names because it has a nice meaning.
I’m voting for [name]Octavia[/name] cause I know you were really taken with that name the other day.
I think [name]Catherine[/name] [name]Octavia[/name] is very nice.
I voted for [name]Violetta[/name] because [name]Violet[/name] is one of my favourites and I think [name]Catherine[/name] [name]Violetta[/name] flows quite well.
[name]Catherine[/name] [name]Aurelia[/name]! [name]Catherine[/name] [name]Ophelia[/name] is beautiful too.
They are all a little too long for my taste… I voted for [name]Aurelia[/name]… [name]Melisande[/name]… And [name]Violet[/name]… Not really a fan of any of them
It’s between [name]Aurelia[/name], [name]Emmanuelle[/name], [name]Melisande[/name], and [name]Octavia[/name] for me. I truly love all four of these names and they all sound lovely with [name]Catherine[/name]. If I had to choose, I would say that [name]Aurelia[/name] and [name]Octavia[/name] have the best ring as a middle for [name]Catherine[/name].
I like a many of them, but personally find [name]Catherine[/name] [name]Verity[/name] (nice mix of sweet and traditional, frilly and grounded, with a little punch) and [name]Catherine[/name] [name]Octavia[/name] (a bit more majestic, but still very feminine and sweet).
I also voted for:
[name]Catherine[/name] [name]Emmanuelle[/name] -it’s such a mouthful, but a very beautiful one. Unexpected and lovely, if not a favorite of mine.
[name]Catherine[/name] [name]Melisande[/name]- like [name]Emmanuelle[/name], it’s just beautiful, even if it’s not a name I like very much myself.
[name]Catherine[/name] [name]Aurelia[/name] - Very pretty, a wee bit expected, but nice.
[name]Catherine[/name] [name]Magdalena[/name] - I like it, but it does remind me a bit much of religion. Probably my own personal quirk.
I don’t really like [name]Hermione[/name], [name]Wisteria[/name], [name]Violetta[/name] or [name]THeophania[/name]. I would like [name]Catherine[/name] [name]Theodora[/name] or [name]Catherine[/name] [name]Theodosia[/name] though. 
Thanks for all the thoughts and votes so far! I’m pleased to see that most of the choices I was leaning toward are getting the most votes, although I’m a little sad that nobody seems to like poor [name]Theophania[/name]. I think it’s such a lovely name with wonderful religious meaning. [name]Theodora[/name] and [name]Theodosia[/name] are nice enough, but I’ve always been drawn to names with spelled with a “ph” ([name]Ophelia[/name], [name]Seraphina[/name], [name]Daphne[/name], [name]Phoebe[/name], [name]Sophia[/name], etc.). It also reminds me of one of my first name loves, [name]Stephanie[/name].
wow, I actually find [name]Catherine[/name] [name]Wisteria[/name] very intriguing!
[name]Catherine[/name] [name]Octavia[/name] is also very beautiful
I voted first for [name]Catherine[/name] [name]Aurelia[/name]. It’s so pretty and soft and the meaning would be “pure gold”!!! I really like your choices and that they are long… The 4 syllable mn balances 2 syllable [name]Catherine[/name] nicely
I voted [name]Catherine[/name] [name]Verity[/name]. Most of your other choices were just too long with [name]Catherine[/name]. I appreciate wanting a more unique middle name with the classic [name]Catherine[/name], but most of these just dont flow well. [name]Catherine[/name] [name]Verity[/name] is very pretty.
I like:
[name]Catherine[/name] [name]Aurelia[/name]
[name]Catherine[/name] [name]Octavia[/name]
[name]Catherine[/name] [name]Verity[/name]
[name]Catherine[/name] [name]Violetta[/name]
My favorite is [name]Catherine[/name] [name]Aurelia[/name].
I find many of the names to be very long unfortunately. A whole lotta syllables in some of them!! I voted for some with less. ([name]Catherine[/name] [name]Violet[/name] would be nicer than [name]Catherine[/name] [name]Violetta[/name] for example!)
Also, are you sure you want a [name]William[/name] and [name]Catherine[/name] sibset? ([name]Prince[/name] [name]William[/name] and the Duchess [name]Catherine[/name] will not be leaving the spotlight anytime soon! Though, maybe it’s not an issue/news-worthy where you live??)
It was a mild concern at first, I admit, but I asked about it in a previous thread and nobody thought it was a big deal since they’re such classic, traditional names. Probably wouldn’t use them for twins, but for a brother and sister, I think it’s fine. Besides, [name]Catherine[/name]'s nickname would be [name]Cate[/name], not [name]Kate[/name], and I’m thinking of using [name]Liam[/name] for [name]William[/name], so that further distances the association. (Not that I would really mind it;. I don’t think of it as a bad one.)
As for those who say most of our choices are too long, I get where you’re coming from, but, personally, I love long, multi-syllable names and think they flow just fine, especially with a last name that’s only one syllable. [name]Just[/name] look at full name of the Duchess herself: [name]Catherine[/name] [name]Elizabeth[/name].
