Jean de Noailles, 5th Duke of Noailles

[3] As a member of the royal military the Duke was away from his estates during much of the French Revolution and was not present for the death of his father, upon which he became the Duc de Noailles.

All were executed except for Adrienne, who was spared at the last moment due to intervention by the future American president, James Monroe (the then U.S. Minister to France), because of her husband's efforts for America during the American War for Independence) but only after her paternal grandmother, mother, and sister were beheaded within her sight.

Through the efforts of his daughter Adrienne de La Fayette, whose husband's family also suffered greatly in the Revolution, some part of his once immense fortune was restored.

[5] On 25 February 1755, he was married to heiress Henriette-Anne-Louise d'Aguesseau, the daughter of Jean Baptiste Paulin d'Aguesseau de Fresne, Count of Compans and of Maligny, and Anne Louise Françoise du Pré, Dame of la Grange-Bleneau.

[6] It was an arranged marriage, worked out by Adrien-Maurice, 3rd duc de Noailles, as Henriette was heiress to the fortune of her paternal grandfather, Henri François d'Aguesseau, a three-time Chancellor of France.
