I find
Oakley very unattractive, but I don't much enjoy either lnfns or tree names, so it was doomed from the start.
As for
Dylan, it's not as if no girl has ever been given a male name! It sounds recognisably like
Lauren and
Sharon etc - not butch, which helps. But, well, I wouldn't use
Leonard on a girl, or
Cohen, or
Bob. That's my issue: I find it a one-owner name, and that owner is male.
But, what do I know? On a needlepoint list, there's a well-respected woman named Maryelvis! Go figure.
