Having recently read two novels with nobles in them, I looked some stuff up.
Prince → Princess, Duke → Duchess, Viscount → Viscountess, Marquess → Marchioness, Baron → Baroness, Earl → Countess.
"Marchioness" is a bit iffy ("Marquess" should have been the female form, with the male shortened to "Marque" or "Marquer"), but someone really messed up with "Countess" being the female equivalent of "Earl". #nobility
