Isabella de Sabran
Isabella de Sabran (1297 – 7 May 1315) was the daughter of Isnard de Sabran and Margaret of Villehardouin, heiress to the Principality of Achaea. In 1314 she married Ferdinand of Majorca, a son of King James II; her mother made over to the couple her claim to Achaea.
She gave birth to James III of Majorca on 5 April 1315 at Catania and died a month later. Ferdinand took up the Achaean claim in the name of their infant son.
