Duke/Legends

A male duke or female duchess was a title of nobility. In many cases, this title was passed down through the family bloodline. The wife of a duke automatically became known as a duchess, regardless of family lineage, and vice versa.

Duchess Satine Kryze was a pacifist aristocrat hailing from Kalevala. During the Clone Wars, she ruled over the New Mandalorians.

Marcha of Mastigophorous was the Duchess of her family at the time of the First Corellian Insurrection.

His Grace the Duke Gadal-Herm's Safety Inspectorate manufactured Jedi Master Yoda's escape pod, and was presumably founded by Duke Gadal-Herm.

During the New Republic era, Grand Duke Gror Pernon encouraged his grand-niece, Plourr Ilo to return to Eiattu with the Rogue Squadron to take back the throne from the impostor prince Harran.
