My top three are:
OctaviaCordeliaAthena
Octavia is fab, I really like it a lot.
Cordelia is also very nice.
Athena is not a name I'd use, but it is still pleasant with a cool history.
I'm not wild about
Sylvia or
Aurelia (my least favourite), and would rank
Edith,
Juliet,
Sabrina,
Cora and
Mabel as OK... none of the names are bad or names I wouldn't like to see irl. I will note that I work with three people with babies named
Mabel! So it seems like it's still going strong popularity-wise, at least in my area.
