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 Élisabeth de Bourbon
Louise Élisabeth had several extramarital affairs, such as her liaison with the handsome Philippe Charles de La Fare. These infidelities incensed her husband, whose jealousy made him turn physically violent against his wife. He is reported to have hurt his wife to the point that she had to see a doctor on two separate occasions. After a particularly dramatic scene in the Conti household, the princess refused to live with her husband anymore and took refuge with her mother. Later she fled to a convent. According to Saint-Simon, she once said of her husband:
he could not make a "prince du sang" without her, while she could make one without him.
The first years of her marriage were full of court cases at the "Parlement de Paris" against her husband due to his violent temper and her desire to leave him. In 1725, she consented to return to the Prince of Conti, who had her confined to the "Château de l'Isle-Adam". She was able later, however, to convince him to allow her to return to Paris in order to give birth to her daughter, Louise Henriette. Her husband died a year later.
