Aurora: I love this, but it's a little overused. In English I just think of this kind of aurora (
https://en.wikipedia.org/wiki/Aurora), not dawn. I've only met 2, one was a dog and we called her that because she looked like a polar bear, and the other was a human who went by
Rory.
Dawn: I know a cool person named
Dawn, but it's a little dated. I don't mind the "
Don" thing; they sound the same in my accent anyway.
Zora: I like this, it's short and cool but not conspicuous at all. It does sound like a name most people would choose just for the sound, with the meaning as a cool bonus. I think this is my favorite of these 4, especially for naming a real baby.
Eos: I like it, but I kinda prefer it genderbent. Not sure if that's weird.
I also love
Alba and
Zoraida.
Ayelet is nice too.
