Françoise de Chalus was the daughter of Gabriel de Châlus, seigneur de Sansac, and Claire Gérault de Solages.
Lady-in-waiting to Louise Élisabeth
On 10 July 1749, she married a noble of Spanish descent Don Jean François, 1er duc de Narbonne-Lara Grandee of Spain1st Class, Lieutenant General of the Army, Commander in Name of the King of the Dioceses of Castres, Albi and Lavaur, 1st Gentleman of the House of H.R.H. the Duke of Parma. Her spouse was a member of the Spanish entourage of Louise Élisabeth of France, who visited the French court at that time. Françoise de Chalus left France for the Duchy of Parma in Italy with her spouse in the retinue of Élisabeth of France, and served for ten years as the lady-in-waiting of Élisabeth of France.
Circumstances around her son
In 1755, she became the mother of Louis, comte de Narbonne-Lara. It is alleged that Louis XV was the biological father. According to documents of the Military Archive, her husband Jean François de Narbonne-Lara had been wounded 8 years earlier in the War of the Austrian Succession, becoming from that moment on unable of having an offspring. The baptism of Louis, comte de Narbonne-Lara is another indication of that paternity. His name was Louis, and his contemporaries remarked about the similarities between Louis and the King.
Lady-in-waiting to Adélaïde
Upon the death of Élisabeth of France in 1759, Françoise de Chalus settled in France, and in 1764, she succeeded the marquise de Civrac as dame d'atour to Madame Adelaide; she was promoted to dame d'honneur after duchesse de Beauvillier in 1781. She reportedly rivaled with the duchess de Civrac, dame d'honneur of Madame Victoire, in an attempt to distance the two sisters. After the accession of Louis XVI in 1774, she belonged to what was called the "Old Court" of the Mesdames at Bellevue. She was described as haughty and imperious, and while Civrac successfully hosted parties in the name of Madame Victoire, Narbonne was reportedly not as successful, as her temperament did not attract people socially. A rumor claimed that it was in fact Madame Adélaïde who was the biological mother of Louis de Narbonne by an incestuous relation to her father, Louis XV. There is nothing to indicate that these rumors were true, though Louis de Narbonne was appointed the chevalier d'honneur of Adelaide, and was reportedly her spoiled favorite as well as the son of her favorite lady-in-waiting, and she reportedly "made enormous sacrifices to his caprices". His mother reportedly regularly made Adelaide pay his debts:
Exile
Françoise de Chalus was the only lady-in-waiting Adelaide allowed to accompany her from the Palace of Versailles after the Women's March on Versailles on the outbreak of the French Revolution on 6 October 1789. In February 1791, she belonged to the large retinue that accompanied Adelaide and her sister Victoire from France to Rome. During their stay in Rome in 1791-96, the court of the Mesdames were divided in two rival fractions lead by the head lady-in-waiting of Madame Adelaide, de Narbonne, and her colleague in the court of Madame Victoire, Angélique Victoire, Comtesse de Chastellux, who were called the Narbonne fraction and the Chastellux fraction.
