Bernard I of Astarac

Bernard I was count of Astarac in Gascony and younger son of Count Sancho I, succeeding his father or elder brother William II. In 1130 he rebuilt fire-damaged Simorre and founded Boulaur monastery. Around 1137 he and his son Sancho founded the Cistercian abbey of Berdoues.

Late in 1141, with his other sons' consent, he gave his middle son Bernard the seigneury of Saint-Martin-du-Gôt. Bernard probably died soon after, in late 1141 or 1142.
