 * Caroline (26 October 1788 – 15 February 1791).

At the outbreak of the French Revolution, he sided with King Louis XVI, as did the rest of his family. In 1789, La Trémoille and his parents emigrated from France, and he joined the émigré army under the Prince of Condé. Two of La Trémoille's brothers perished in the Reign of Terror. His wife was imprisoned in the prison de l'Abbaye until 1792, when she was permitted to join him in England. She became a writer and left England in company of her brother-in-law Marie François Emmanuel de Crussol for the court of Russia around March 1797, where she was a maid of honour of Empress Maria Feodorovna.

After the Revolution, La Trémoille returned to France. Following Louise Emmanuelle's death, he remarried in 1817 to Marie Virginie de Saint-Didier. They had two daughters:
