Louise Marie Madeleine Fontaine
On 9 October 1749 at the Church of Saint-Sulpice, Paris, Jacques-Armand Dupin married with Louise-Alexandrine-Julie de Rochechouart-Pontville. But for Louise and her husband, their son was a source of many troubles, especially when he ran up debts of very large sums of money from gambling. His father had to sell many of his assets in 1750 to honor the debt of his son. The troubles with Jacques-Armand, however, continued. Claude Dupin was forced to obtain against him a "Lettre de cachet", who imprisoned Jacques-Armand in the fortress of Pierre Encise under the pretext of madness. After this, the family decided to send him to the Île Maurice (26 October 1765), where he remained for the next two years until his death on 3 May 1767, a victim of yellow fever. Before embarking on the "Count of Artois", a merchant ship of the French East India Company, Jacques-Armand reportedly revealed to his mother the existence of an illegitimate daughter of his, called Marie-Thérèse Adam, whose origins, however, remained mysterious. Nevertless, Madame Dupin took care of the child and raised as her own, later becoming in her reader and heiress. Louise considers Marie-Thérèse as her own daughter and educated after her own image, transmitting her high culture and elegance of her manners. Marie-Thérèse Adam was entirely dedicated to Madame Dupin and remained at her side until the last moment.
Jean de Ferrières
Jean de Ferrières, Vidame de Chartres, was the grandson of Jean de Ferrières (died 1497), who had been twice married, firstly to Marguerite de Bourbon (d. before February 1482), illegitimate daughter of John II, Duke of Bourbon (d. April 1488), by whom he had two sons who died without issue, and secondly to Marie de Damas, Dame de Maligny, by whom he had an elder son, Philippe de Ferrières, who inherited the Ferrières lands, and a younger son, François de Ferrières (died 1544), who inherited the Maligny lands, and in 1516 married Louise de Vendôme (d. by 1553), despite the strong opposition of her brother, Louis de Vendôme (d. 22 August 1526). François de Ferrières (died 1544) who was chamberlain to Charles, Duke of Bourbon, and Louise de Vendôme, who was maid of honour to Anne de Beaujeu, Duchess of Bourbon, had two sons and five daughters:In February 1538 Jean de Ferrières was given two benefices by his father. Less than two years later, however, he was disinherited by both his father and mother when they made their joint last wills on 23 December 1539. Although the reason for his disinheritance is unknown, d'Estang suggests that it may have been due to his abandonment of the Catholic religion.
