Surprisingly, both Francois III and Francois IV were Protestants. The former had married the sister-in-law to the Prince de Condé and was killed in the St. Bartholomew Day's Massacre. The latter was also killed but at Saint-Yrieix by the French Catholic League.
These would be the last Protestant Lords Rochefoucauld. Francois V was raised into Duc de La Rochefoucauld by Louis XIII in 1622; his Catholicism may well have been the reason for the elevation since his predecessors had been denied the title.
The male line died out in 1721; by patent of Louis XV the title was permitted to be carried by Marie-Louise de La Rochefoucauld's male children (she was the daughter of Alexandre I). However, there was a condition. In order for Marie-Louise to obtain the title for her sons she would have to marry one of her Rochefoucauld-relations. She chose Jean Baptiste de La Rochefoucauld de Roye.
The son of Marie-Louise and Jean Baptiste had inherited no less than two ducal titles: Duc de La Rochefoucauld and Duc d'Anville. He would be known as the Duc de La Rochefoucauld-d'Anville. He would meet a grisly end in 1792 when he was assassinated in the massacre of September that year. His cousin, Francois XII, has gone down in history for his comment to Louis XVI on 12 July 1789. When the King asked if it was a revolt, Francois answered "No, sire, it is a revolution".
The family line is still in existence with the Francois de La Rochefoucauld claiming the unofficial title of the 14th Duc de La Rochefoucauld.
