In July 1131, Aimery was at the deathbed of his half-brother to witness his final testament, of which he was to be the executor. Aimery died in battle before the walls of the Moorish city of Fraga, which Alfonso had been besieging. Aimery had a son and a daughter by Ermengard; the son, Aimery, predeceased him (ca. 1130), and he was succeeded by his daughter Ermengard, who was only four or five at the time. He married a second time to a woman named Ermessende and left by her a daughter of the same name. This second daughter, Ermessende, married before 1153 a great Castilian magnate, Manrique Pérez de Lara, lord of Molina.
