“ Adélaide married in 1779 Alexandre Sebastien de Flahaut de la Billarderie, comte de Flahaut, a soldier of some reputation, who was many years her senior. In Paris she soon gathered round her a salon, in which the principal 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 generally known to be Talleyrand’s son.
