I like the sound of
Lilith, but not the association - though more for cultural than religious associations. She isn't a figure at all in
Christian teaching, or not any branch that I'm familiar with at least. But the name does have that sort of negative cast to it. It would feel more like trying to be "edgy" than anything else.
Meanwhile, I like the sound of
Eve and I don't have a problem with its associations. I prefer
Eve to
Eva, there's just a certain sort of solidness to it.
