SOUZA-BOTELHO, ADELAIDE FILLEUL, MAR QUISE DE (1761-1836), French writer, was born in Paris on May 14, 1761. Her mother, Marie Irene Catherine de Buisson, daughter of the seigneur of Longpre, near Falaise, married a bourgeois of that town named Filleul. It was reported, though no proof is forthcoming, that Mme. Filleul had been the mistress of Louis XV. Her husband became one of the king's secretaries, and Mme. Filleul made many friends, among them Marmontel. Their eldest daughter, Julie, married the marquis de Marigny (1727-1781) ; Adelaide married in 1779 Alexandre de Flahaut de la Billarderie, comte de Flahaut, who was many years her senior. In Paris she soon gathered round her a salon, in which the prin cipal figure was Talleyrand. There are many allusions to their liaison in the diary of Gouverneur Morris. In 1785 was born her son Auguste Charles Joseph de Flahaut (q.v.), who was gen erally known to be Talleyrand's son. Mme. de Flahaut fled from Paris in 1792 and joined the society of émigrés at Mickleham, Surrey, described in Mme. d'Arblay's Memoirs. Her husband re
mained at Boulogne, where he was arrested on Jan. 29, 1793, and guillotined. Mme. de Flahaut now supported herself by writing novels, of which the first, Adele de Senange (London, which is partly autobiographical, was the most famous. She pres ently left London for Switzerland, where she met Louis Philippe, duke of Orleans. She travelled in his company to Hamburg, where she lived for two years, earning her living as a milliner. She returned to Paris in 1798, and in 1802 she married Jose Maria. de Souza-Botelho Mourao e Vasconcellos (1758-1825), Portu guese minister plenipotentiary in Paris. Mme. de Souza lost her social power after the fall of the First Empire. She died on April 19, 1836. She brought up her grandson, Charles, duc de Morny, her son's natural son by Queen Hortense.
