Many titles are gender neutral, but you can certainly pick out female specific titles if you go looking. Countess (establishes nobility), Dame (implies knighthood), Landbride (establishes real estate ownership, implies nobility).
The issue with Maenad is that it's a D&D race, with different connotations than the bacchanalian. Celebrant is the closest title that comes to mind.
And titles need not be formal in style. Soothsayer, Wisdom, Teacher, Churigeon - all meaningful titles.
If you want to go really out there: Pair, Duo, Team; They, them, their, theirs, themselves. Argue that <charname> should be a Dvati.
