If we're taking Oedipal names,
Jocasta wins hands down :-)
I pronounce
Ismene closer to is-MEY-ney, so the 'is a meanie' thing isn't immediately apparent...but I've never actively considered any of these names. The connotations are just way too strong.
Antigone has a nice rhythm, but in addition to the 'anti-gone' thing, it sounds like a medical condition, or some sort of sinister plant or chemical...but only in my head :-P
