Auguste Charles Joseph, Comte de Flahaut de la Billarderie, a French soldier and diplomat, was believed to be the illegitimate son of Talleyrand. He was the paramour of Napoléon's sister Caroline Murat and of Napoléon's adopted daughter Hortense de Beauharnais, whose son by him became Duke of Morny, Emperor Napoléon III's half-brother. Flahaut was exiled during the reign of the two last Bourbon kings and returned to France in 1830, being ambassador at Vienna 1842-1848 and London 1860-1862.
