Styled the Prince of Turenne as the heir apparent to Bouillon, he married Princess Louise Henriette Gabrielle de Lorraine on 27 November 1743.

She was a member of the house of Lorraine and a great grand daughter of Henri, Count of Harcourt.

The widower Duke married again in 1789 to Marie Françoise Henriette de Banastre (1775–1816), a girl who was some forty-seven years younger than he.

In just three months, he squandered almost a million livres on his mistress, an opera singer, thus bringing his family to the verge of ruin.

He died at the Château de Navarre on the eve of the French Revolution and was succeeded by his eldest son Jacques, who was an invalid.
