Roger d'Armagnac

Roger d'Armagnac (c. 1277–1339) was a churchman of the comital house of Armagnac: son of Count Géraud VI and Marthe of Béarn, and nephew of Archbishop Amanieu II of Auch. As archdeacon of Agen he was named by Pope John XXII in 1317 the first bishop of the newly created diocese of Lavaur.

In 1319, after his brother Count Bernard VI died, the pope allowed Roger to act as guardian of Bernard's minor children. At Lavaur he enlarged the canons' cloister, consecrated the cathedral's high altar and joined Notre-Dame de Péchaudier to the provostship. He was translated to Laon in 1336 and died in 1339.
