Petronilla of Aquitaine

Petronilla accompanied her sister to the French court, where she met Count Raoul I of Vermandois, who was a married man and a cousin to her brother-in-law Louis VII of France. He repudiated his wife and married her, and they were excommunicated by Pope Innocent II in 1142. Hostilities broke out, and Louis VII infamously burned Vitry-en-Perthois in 1145. Pope Eugenius III renewed the excommunication in 1145, but eventually lifted it at the Council of Reims in 1148. The exact date of Petronilla's death is unknown, although she must have died at some point between the Council of Reims in 1148 and 1152 when Raoul was married for a third time to Laure, daughter of Thierry of Alsace, count of Flanders. Petronilla was buried in the Cluniac priory of Saint-Arnoul in Crépy-en-Valois, where Raoul was later interred alongside her. ==Issue==

Together Raoul and Petronilla had three children: • Elisabeth, Countess of Vermandois also known as Isabelle Mabile (1143 – 28 March 1183), married Philip, Count of Flanders. • Ralph II, Count of Vermandois (1145–1167), married Margaret I, Countess of Flanders. • Eleanor, Countess of Vermandois (1148/49 – 1213), married four times. ==In fiction and literature==
