Jordan III of L'Isle-Jourdain

Jordan III (c. 1150–1200) was Lord of L'Isle-Jourdain, succeeding his father Jordan II in 1196. In 1175 he married Esclarmonde of Foix, daughter of Count Roger-Bernard I of Foix; the marriage produced six children, among them his heir Bernard Jordan.

He warred with Bernard of Comminges until the count of Toulouse made them lay down arms at Verdun-sur-Garonne. He was dead by October 1200, when his widow turned to Catharism and became a leading Perfect.
