Henriette-Lucy, Marquise de La Tour du Pin Gouvernet

Henriette-Lucy Dillon was born into a prominent Irish Wild Geese Jacobite military family in France. She was daughter of Arthur Dillon, colonel-proprietor of the Dillon Regiment, and the lady-in-waiting Therese-Lucy de Rothe (1751–1782). Her father had been born in England, so she was often regarded in France as English. However the family, of Norman descent, was linked to the Dillons of Costello-Gallen and the lords of Drumraney in Ireland, who were granted lands in County Westmeath in the thirteenth-century.

Following her mother's death and her father's subsequent posting abroad, where he remarried, Lucie lived in the household of her grandmother, Mme. de Rothe, and Arthur Richard Dillon, Archbishop of Narbonne, until joining the Court of France. She married Frédéric, comte de Gouvernet, later Marquis de La Tour-du-Pin, an army officer and diplomat, in 1787. He was the son of Jean-Frédéric de la Tour du Pin-Gouvernet, a French Minister of War.

Following her mother she served as an apprentice lady-in-waiting to Marie Antoinette, Queen of France, from the age of 16 in 1787, until 1789.

She was present at Versailles during the Assembly of the Estates, and witnessed the Women's March on Versailles at the outbreak of the French revolution. She also witnessed the peasant uprising called the Great Fear in the countryside.

Between October 1791 and March 1792, her husband served as ambassador in the Hague, where she joined him, returning to France only in December 1792.

During the Reign of Terror of Robespierre in 1793, many of her friends and family were executed and she fled Paris for the family estate of Le Bouilh, or Saint André Bouilh Cubzac in the Gironde region. During the summer of that year, their estate was seized by the government, and her husband was imprisoned. She managed to secure his release from Jean-Lambert Tallien by the help of Thérésa Tallien.

Directly after his release, she, aged 24, and her husband passed into exile for a new life on a dairy farm near Albany in Upstate New York. Although they were never officially listed as émigrés, Frédéric had been living in hiding prior to departure. She described this time as the happiest of her life. She vividly describes the reality of owning slaves and interactions with the local Dutch families and the few remaining Native Americans of the area.

She was close to Talleyrand during his exile in the United States, and she returned to France as he did after the establishment of the Directorate, in 1796. The couple left the United States because her husband wanted to resume his career in public life and shore up the family fortunes.

After the French coup of 1799, which brought Napoleon to power, her husband was able to resume his diplomatic career. She was able to promote his career under Napoleon, who was looking for aristocrats to lend legitimacy to his power and, from 1804, his court. Her memoirs described an insider's view of many events from the Imperial court of Napoleon.

She continued to follow her husband to his various diplomatic appointments after the Bourbon Restoration. They went into effective exile again after their son Aymar became involved in the anti-Orléanist plot of Caroline Ferdinande Louise, duchesse de Berry, in 1831, in the Vendée. Aymar escaped France, but was condemned to death in his absence. The family sold its possessions in France soon after.

Following her husband's death in Lausanne, Switzerland in 1837, she moved to Italy, where she died in Pisa, Italy
