Petronilla married Gaston, Viscount of Béarn, and when he died without issue, in 1215, took as number two Nûnez de Cerdagne, but tired of him speedily, got the marriage annulled, on the convenient plea of consanguinity, and married in 1216 Guy, son of Simon de Montfort. This was sharp work--three husbands in a twelvemonth. By Guy she had two daughters, Alix and Perette. In 1228 she took a fourth husband, Aimart de Rançon, and on his death, in the same year, she espoused her fifth, Boso de Mastas, to whom she bore a daughter, Martha. By her will Petronilla constituted Esquirat, eldest son of her daughter Alix, heir to her estates and titles; but in default of male issue the succession was to go to Jordan, the second son of Alix. Should he fail to have a son, then the second substitution was in favour of Martha, her daughter by Boso, who was married to Gaston VII of Béarn. Esquirat did have a son, also named Esquirat, but this second Esquirat died childless, and bequeathed the county of Bigorre to his sister Lore, as his uncle Jordan had died without issue. Now Petronilla and her third husband Guy de Montfort had left a second daughter, Perette, married to Raoul de Teisson, and had by him a son William de Teisson, who conceived that he had a right to the inheritance. Martha, wife of Gaston de Béarn, had a daughter Constance, and she also put in a claim. In fact, these were the claimants: Lore, Viscountess de Turenne; Constance, Viscountess de Béarn; William de Teisson; and Mahut, daughter of Alix and Raoul de Courtenay. But that was not all. The younger Esquirat had made over his inheritance to Simon de Montfort by a first will, and then, offended at the grasping nature of Simon, had revoked his will and constituted Lore his heiress. But Simon refused to recognize the legality of this second will, sold the viscounty to Thibalt II, King of Navarre, whose son Henry gave his claim to it to Jeanne, his daughter, married to Philip the Fair, King of France, and he was but too ready to acquire this rich district of Gascony on any plea, bad or good. The church of Le Puy also put in a claim, so did the King of England as overlord. Consequently there were from eight to nine claimants. By decree of Parliament, in 1290, the rights of the church of Le Puy to the charge on the viscounty were confirmed. Constance, Viscountess of Béarn, occupied Bigorre with her troops, and assumed the title of Countess of Bigorre. Jeanne of France, however, expelled her, adopted the title, and Philip the Fair asserted his right to the territory, and was prepared to maintain it by force of arms. Philip had already bought off the rights of the church of Le Puy. Bigorre remained under the crown of France till Charles VIII in 1425 granted it to John, Count of Foix, in return for his services against the English, and in consideration of his descent from Petronilla.
