Houses Minor are a well established part of the Dune Universe, being mentioned in passing many times. But I can't recall a single character from a Minor House.
The Siridar Titles of the Major houses are a jumble, Duke, Count, Baron seem to be randomly assigned to houses. Atreides holds a single world (Caladan is a valuable agricultural world) and the Harkonnens hold 2 (Geidi Prime, which surely has a GDP multiple times what Caladan's is, and Lankviel a less important agricultural world) and are governors of the most valuable world (Arrakis), yet Leto is a Duke and Vladimir is just a Baron.
Did the heads of Minor Houses even have a title? If so what were their titles?
