Бриссак
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). After Timoléon de Cossé-Brissac died in 1848, the title of Duke of Brissac was held by his successive descendants in the male line.
