I do find
Aureliana too frilly. I absolutely love
Aurelia, and would leave it at that. The extra letters at the seem unnecessary and it crosses the border into "my precious little princess" territory.
I've never been too fond of Aurelian, but I don't outright dislike it. I guess it's just because I love
Aurelia so much that I could never consider Aurelian for my own kid.
