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.
Louise Henriette de Bourbon
The couple had three children:Louise Henriette died on 9 February 1759 at age 32, with her husband and children at her side, at the Palais-Royal, the Orléans residence in Paris. Her son and daughter were, respectively, eleven and eight years old. After her death, her husband had several mistresses, ultimately finding the love of his life, the witty but married marquise de Montesson, whom he married after she became a widow. Like her mother, who had inherited the title through her Condé's ancestry, Louise Henriette was the "duchesse d'Étampes" in her own right, having inherited the title on the occasion of her husband's rise to the head of the House of Orléans in 1752. At her death, her son inherited the ducal title, which he held until it became extinct in 1792, during the French Revolution.
