Biography
Family
Born on May 7, 1728, Marie-Christine was the granddaughter of the memoirist Louis de Rouvroy, Duke of Saint-Simon. She was the daughter of his eldest son, Jacques-Louis de Rouvroy (1698–1746), Duke of Saint-Simon by gift inter vivos, known as the "Duke of Ruffec", and his wife Catherine-Charlotte-Thérèse de Gramont (1707–1755). Jacques-Louis died in 1746. His brother, Jean-Armand (1699–1754), Count of Rasse, Grandee of Spain, became Duke of Saint-Simon. Since his father was still alive, Jean-Armand was in turn called the "Duke of Ruffec".
Marriage
On December 10, 1749, in the chapel of the Hôtel de Saint-Simon in Paris (with the approval of King Louis XV, dated November 1), Marie-Christine married Charles-Maurice Goyon de Matignon, known as "the Chevalier de Monaco," Count of Valentinois, descended from the Grimaldi family through his mother, and brother of the sovereign Prince Honoré III of Monaco. Jacques, Duke of Valentinois, Marie-Christine's father-in-law, gifted her the Hôtel de Valentinois in Passy.
Grandee of Spain
In 1752, her uncle Jean-Armand made Marie-Christine his sole heir. He died in 1754, and Marie-Christine became Countess of Rasse and Grandee of Spain of the first class. In the House of Saint-Simon, in fact, the title of Grandee passed to women, in the absence of men. A few years earlier, in his Memoirs, Marie-Christine's grandfather had mentioned instances of Grandeeships that substituted, "in a few houses or on uncommon occasions, for the paternal uncle to the niece." Charles-Maurice became Grandee of Spain of the first class, jure uxoris. Since 1701, Grandees of Spain in France had "the rank, honors, treatment, and distinctions of dukes." On June 4, 1754, as a Grandee of Spain, the Countess had the honor of greeting Louis XV and Queen Marie Leszczyńska. She was entitled to the stool. In 1755, upon the death of her grandfather, the memoirist, she inherited the Château de la Ferté-Vidame.
On October 27, 1762, she was appointed lady-in-waiting to Mesdames. In December, she sold her estate in Ruffec to Charles-François de Broglie. On June 21, 1764, she sold her château de La Ferté-Vidame to the financier Jean-Joseph de Laborde.
The Count and Countess of Valentinois had no children and separated in 1766. In 1770, Marie-Christine was appointed dame d'atours (lady of the wardrobe) to the Countess of Provence, and was later promoted to dame d'honneur (lady of honour) in 1772. She died in Paris on 15 July 1774, bequeathing the Hôtel de Valentinois to her cousin, Count Jacques de Stainville.
