September 1792, he was killed during the September Massacres at Versailles. His body was butchered and his head severed. The head was wrapped in a cloth and carried by a peasant mob to the Château de Louveciennes where it was thrown through an open window, landing in the salon of his lover, Madame du Barry. After the death of Louis-Hercule in 1792 without a living male-line descendant, the ducal title passed to Timoléon de Cossé-Brissac (1775–1848). He was the eldest son of Hyacinthe-Hugues de Cossé-Brissac, Duke of Cossé (1746–1813), whose father was René-Hugues de Cossé-Brissac, Count of Cossé (1702–1754). René-Hugues was the third son of Artus de Cossé-Brissac, 5th Duke of Brissac (1668–1709), the father of the 6th and 7th Dukes of Brissac. After Timoléon de Cossé-Brissac died in 1848, the ducal title was held by his successive descendants in the male line, including François, 11th Duke of Brissac, Pierre, 12th Duke of Brissac, and François, 13th Duke of Brissac. The current holder of the ducal title is Charles-André de Cossé-Brissac, 14th Duke of Brissac. The heir apparent to this title is his eldest son, Laszlo de Cossé-Brissac, Marquis of Brissac.
