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.
Chateau and Seigneurie de Launay
Three children were born to André Guyonneau and his wife, Anne Gabrielle Harrison d’ Auvours. Two boys died as young children. A daughter, Anne Françoise, was born 1 December 1772. She married Jacques Louis Belin de Béru (twice her age at the time of their wedding in January 1796). Despite the seizure of property by the Republic, Anne was quite wealthy at the time of her marriage; her most valuable asset was the Domaine of Grandmaison. Louis was imprisoned in Paris during the Terror. He would have been executed if not for the timely fall from power of Robespierre. Louis went on to have a long and successful career in the National Assembly. He died at age 81 in 1828; Anne died 14 September 1840. At the time of her death the Domaine de Grandmaison included 125 ha. The holdings included the chateau as well as named properties: la Furetière, la Chalopinière, les Petits and Grand Guéraule and le Degoutier. Anne and Jacques de Grandmaison had no children. Thus, after eight centuries, the powerful Domaine de Launay was poised to be dismembered.
