Louise d'Aumont

Louise d'Aumont, duchesse d'Aumont, duchesse Mazarin et de La Meilleraye (Louise Félicité Victoire; 22 October 1759 in Paris – 13 December 1826 in Paris) was the only child and daughter of Louis Marie d'Aumont, Duke of Aumont (1732–1799), and his wife, Louise Jeanne de Durfort, duchesse Mazarin et de La Meilleraye (Paris, 1 September 1735 - Paris, 17 March 1781).

She married Honoré IV, Prince of Monaco, on 15 July 1777 in Paris.

The couple had two children, both of whom in turn ruled Monaco: Prince Honoré V and Prince Florestan I. Following their incarceration during the French Revolution, the marriage of Honoré IV and Louise ended in divorce in 1798. On 28 March 1794, Louise gave birth to an illegitimate daughter, Amélie Céleste Erodore d'Aumont (died 1820). Louise married secondly René François Tirnand-d'Arcis on 6 February 1801. This marriage too ended in divorce in 1803.

Louise d'Aumont was a direct descendant of Hortense Mancini, the mistress of King Charles II of England, who was one of the two heiress of her uncle, King Louis XIV's chief minister Cardinal Mazarin.

Through their descent from Louise and her mother, the princely family of Monaco now lays claim to the wealth and estates bequeathed by Cardinal Mazarin, including the Duchy of Rethel, and the Principality of Château-Porcien.
