Her younger brother, Gaston Jean Baptiste Charles, was the husband of Marie Louise de Rohan,[1] future governess of Louis XVI and his siblings.

She was engaged to Godefroy de La Tour d'Auvergne, only son and heir of Charles Godefroy de La Tour d'Auvergne and his Polish born wife Maria Karolina Sobieska.

The couple's marriage was carried out by the Cardinal d'Avergne, her husband's cousin; they wed in the Hôtel of her younger brother, Louis Camille de Lorraine.

At the death of her father in law Charles Godefroy de La Tour d'Auvergne, her husband became the Duke of Bouillon.

She has no known surviving descendants; the Princes of Guéméné (members of the House of Rohan) claim the Duchy of Bouillon via Louise's sister in law Marie Louise de La Tour d'Auvergne who married the Prince of Guéméné and has descendants in modern Austria.
