You may also be looking for the similar title, Prelate.

The First Prelate was the leader of Drayan II and the Drayan people.

In 2372, First Prelate Alcia held this position, while the USS Voyager made first contact with her species. (VOY: "Innocence")

The fact that the First Prelate seen in the episode was a descendant of a person said to have helped the Reformation occur might indicate hereditary leadership.
