“ The birth of their son was registered in Paris on the 21st of October 1811 as Charles Auguste Louis Joseph Demorny, known later as the duc de Morny. Flahaut fought with distinction in the Russian campaign of 1812, and in 1813 became general of brigade, aide-de-camp to the emperor, and, after the battle of Leipzig, general of division. ”

“ He remained intimately associated with Talleyrand’s policy, and was, for a short time in 1831, ambassador at Berlin. He was afterwards attached to the household of the duke of Orleans, and in 1841 was sent as ambassador to Vienna, where he remained until 1848, when he was dismissed and retired from the army. After the coup d’état of 1851 he was again actively employed, and from 1860 to 1862 was ambassador at the court of St James’s. He died on the 1st of September 1870. ”

“ He was saved from exile by Talleyrand’s influence, but was placed under police surveillance. Presently he elected to retire to Germany, and thence to England, where he married Margaret, daughter of Admiral George Keith Elphinstone, Lord Keith, and after the latter’s death Baroness Keith in her own right. The French ambassador opposed the marriage, and Flahaut resigned his commission. His eldest daughter, Emily Jane, married Henry, 4th marquess of Lansdowne. ”
