The Book Of Nod offers the following:

the Kingship Clan (Ventrue)
the Clan of the Beast (Gangrel)
the Moon Clan (Malkavian)
the Clan of the Hidden (Nosferatu)
the Wanderer Clan (Ravnos)
the Clan of the Rose (Toreador)
the Night Clan (Lasombra)
the Clan of Shapers (Tzimisce)
the Snake Clan (Followers Of Set)
the Clan of Death (Cappadocian)
the Healer's Clan (Salubri)
the Clan of the Hunt (Banu Haqim)
the Learned Clan (Brujah)

I agree that Patrician works better than King for Roman Ventrue, and Serpent...
