Her father was a son of Godefroy Maurice de La Tour d'Auvergne and his wife, Marie Anne Mancini, the latter was a niece of Cardinal Mazarin and an infamous hostess in her day.

In 1741, her maternal uncle Louis de Lorraine-Harcourt[3] was a proposed candidate for the hand of the 12-year-old, but the marriage never materialised and he died childless in 1747.

She married Prince Charles Juste de Beauvau-Craon, a member of the wealthy Beauvau family of the Duchy of Lorraine, on 3 April 1745.

She died of smallpox[1] at the Hôtel de Beauvau-Craon, her husband's town house in Lunéville, Lorraine.

Notwithstanding the utmost care,[1] she succumbed to the illness; at the time she was arranging the proposed marriage between her daughter Louise and Armand Louis de Gontaut, Duke of Lauzun.
