Ethel is ugly. I think
Eleanor and
Evelyn are unattractive too, but they're not as objectively ugly; they have a certain elegance to them that
Ethel is missing.
Candace and
Cynthia are not ripe for a comeback yet; it hasn't been 100 years. I also think
Candace may have been too much of a fad with no staying power.
Cynthia will come back when it's time.
I'm not sure it's been long enough for
Kirk either, but it does sound a lot like
Clark, which is rising in popularity. I wouldn't be surprised if it spiked soon.
