I rather like
Bridget.
My personal association with the name is actually
Kaley Cuoco's
8 Simple Rules character.
I'm not sure if I associate it with timelessness, though I have encountered folks of a wide variety of ages with the name.
Anyway, I'm not sure if I consider it "pretty," but I do quite like it.
