Guy de Montfort, Count of Bigorre explained

Guy de Montfort (died 1220) was the Count of Bigorre^[1] from 6 November 1216 to 1220 in right of his wife, Petronilla. He was a son of Simon de Montfort, 5th Earl of Leicester^[2] and Alice of Montmorency.

Guy joined his father on the Albigensian Crusade while still quite young.^[3] Late in 1216, he married Petronilla, the heiress to Bigorre and Marsan through her mother Stephanie, and a daughter of Bernard IV of Comminges.^[4]

He fought at his father's side at the siege of Toulouse in 1218, but his father died: crushed by the projectile of a siege engine.^[5] Guy's oldest brother Amaury de Montfort inherited their father's command, but not his strategic vision. The Occitan lords rebelled against him and Guy was killed in a conflict at Castelnaudary in 1220, either on 4 April or in July.^[6]

Guy left a daughter, Alice, who succeeded Petronilla as Countess of Bigorre. He also left a daughter named Pernelle, who married Raoul de la Roche-Tesson.
