Bernard of Fézensaguet

Bernard of Fézensaguet (c. 1155–c. 1191), also called Bernard de Lomagne, was the eldest son of Odon de Lomagne, lord of Firmacon, and Mascarose, daughter of Count Géraud III of Armagnac. In 1184 his uncle Count Bernard IV adopted him, named him heir to Armagnac and Fézensac should he have no children, and enfeoffed him with Fézensaguet.

Bernard IV was succeeded by his own son Géraud IV, but Bernard's son Géraud V inherited the counties in 1215 and began the second House of Armagnac.
