Loving this name. Not sure if it sound to made up. Time is running out! Also considering [name_f]Aurelia[/name_f] [name_m]Christian[/name_m] and [name_f]Emma[/name_f] [name_f]Violette[/name_f]. A boy would be Skander [name_u]Finn[/name_u]
[name_f]Carina[/name_f] does not sound made up to me. Incidentally, I believe [name_f]Violette[/name_f] and [name_f]Violet[/name_f] would be pronounced differently… emphasis on the last syllable -ette with [name_f]Violette[/name_f], and emphasis on the first syllable [name_f]Vi[/name_f]- for [name_f]Violet[/name_f]. I prefer [name_f]Carina[/name_f] [name_f]Violet[/name_f].
Skander [name_u]Finn[/name_u] is fabulous!
I like [name_f]Carina[/name_f] [name_f]Violet[/name_f], but [name_f]Carina[/name_f] [name_f]Violette[/name_f] feels a bit too frilly for me. I’m not generally a fan of extra letters on names like [name_f]Violet[/name_f], [name_f]Juliet[/name_f], [name_f]Isabel[/name_f] and [name_u]Vivien[/name_u] - I think they’re more strikingly beautiful with the simpler endings. Same thing with [name_f]Emma[/name_f] [name_f]Violette[/name_f], though being a simpler name I think you can get away with the extra letters better than with [name_f]Carina[/name_f]. I still prefer [name_f]Emma[/name_f] [name_f]Violet[/name_f] though, which is gorgeous!
[name_f]Aurelia[/name_f] [name_m]Christian[/name_m] is nice, though [name_m]Christian[/name_m] seems decidedly masculine for your tastes (looks a bit odd alongside names like [name_f]Carina[/name_f], [name_f]Aurelia[/name_f] and [name_f]Violette[/name_f]). It’s different and unexpected though, and I like it. I also love [name_f]Aurelia[/name_f] [name_f]Violet[/name_f].
I dislike [name_f]Carina[/name_f]. [name_f]Emma[/name_f] [name_f]Violet[/name_f] or [name_f]Aurelia[/name_f] [name_f]Violette[/name_f] are way better imo.
I went to college with a [name_f]Carina[/name_f] and a [name_f]Karina[/name_f]. I definitely prefer the [name_f]Carina[/name_f] spelling.
I like [name_f]Emma[/name_f] [name_f]Violet[/name_f] and [name_f]Carina[/name_f] [name_f]Violet[/name_f] the best. Despite [name_f]Emma[/name_f]'s popularity, I prefer the name. As others have said, I am not of a fan of the [name_f]Violette[/name_f] spelling. I think it adds some fussiness without any actual substance.
I haven’t ever been a fan of [name_f]Aurelia[/name_f]. [name_f]Aurelia[/name_f] [name_m]Christian[/name_m] is a bit unexpected in a good way.
[name_u]Love[/name_u] [name_f]Carina[/name_f] - so very pretty and definitely not made up - and flows beautifully with [name_f]Violette[/name_f]!
I would certainly choose [name_f]Violet[/name_f] though. [name_f]Violet[/name_f] is lovely, [name_f]Violette[/name_f] just looks odd to me. I do agree with a previous poster about the simple forms of names seeming more strong and beautiful. E.G. I strongly prefer [name_f]Annabel[/name_f] to [name_f]Annabelle[/name_f].
[name_f]Carina[/name_f] [name_f]Violet[/name_f] (or even [name_f]Violette[/name_f]) is a gorgeous name though. 
My googling says [name_f]Carina[/name_f] isn’t made up–it’s derived from cara, “dear” or “beloved.” Among your list, I like [name_f]Emma[/name_f], though I prefer [name_f]Violet[/name_f], but if you love [name_f]Carina[/name_f], go for it! Re [name_f]Aurelia[/name_f] [name_m]Christian[/name_m]: not a fan of boys’ names on girls, so I think it’d be better if you use a feminine version, like [name_f]Christiane[/name_f], [name_f]Christina[/name_f], [name_f]Christine[/name_f], or [name_f]Christiana[/name_f].
