Thanks to the generosity of Samuel Bernard and his income of the "Ferme générale", Claude Dupin could obtain a considerable fortune, mainly in lands. Monsieur and Madame Dupin occupy a privilege position and had a lavish lifestyle. On 12 April 1732 Claude Dupin, jointly with his mother-in-law Manon Dancourt, bought the prestigious Hôtel Lambert in the Île Saint-Louis for the sum of 140,000 livres. On 9 June 1733 he acquired the magnificent Château de Chenonceau from the Duke of Bourbon for 130,000 livres. Each year, the Dupins spent the autumn in the Touraine. Starting in April 1741, Louise, with her husband, son and stepson, remained in the Hôtel de Vins, located in the Parisian Plâtrière street and from 1752 they also owns a house in Clichy-sur-Seine where they spend the summer months. On 24 April 1738 with the acquisition of the Marquisate of Blanc and the Castellany of Cors, located at the limits of Berry and Poitou, they completed their patrimony. The Marquisate of Blanc includes the "Château-Naillac", the "château de Roche", the "Château de Rochefort", "Château de Cors", "Château de Forges", with his respectives properties, farms, ponds and lands, who produced a total of 555,000 livres, four times the prize of Chenonceau. But soon difficulties arosed with the Countess of Parabère, the former owner, who caused the sequestration of Blanc lands and only after a decree of the Parlement of Paris dated 2 September 1739, confirmed by a judgment of 11 December, confirmed Claude Dupin as the legitimate owner of this lands and could recovered them.
Louise Marie Adélaïde de Bourbon, Duchess of Orléans
In the summer of 1772, a few months after his wife had given birth to a stillborn daughter, Philippe's secret liaison began with one of her ladies-in-waiting, Stéphanie Félicité Ducrest de St-Albin, Comtesse de Genlis, the niece of Madame de Montesson, the morganatic wife of Philippe's father. Passionate at first, the liaison cooled within a few months and, by the spring of 1773, was reported to be "dead". After the romantic affair was over, Félicité remained in the service of Marie-Adélaïde at the Palais-Royal, a trusted friend to both Marie-Adélaïde and Philippe. They both appreciated her intelligence and, in July 1779, she became the governess of the couple's twin daughters born in 1777.
