I prefer
Aurélie. There's a newsreader on a local radio station named
Aurélie - I can never catch her ln, probably because it seems to come from Francophone
Africa somewhere! And she's very good.
Aura is too much of a word, and a rather silly word at that. All touchy-feely pseudo-spiritual.
Aurelia is a mouthful, and sounds pretentious to me.
Aurea? No. Like gilding refined gold or painting a lily.
Aurora is better than dreary
Dawn, but too balletic.
