The late Sir Alexander Duff-Gordon.—Our obituary yesterday contained the name of a gentleman well-known in London society — Sir Alexander Cornewall Duff-Gordon, one of the Commissioners of Inland Revenue. He was the eldest son of the late Sir William Duff-Gordon, a cadet of the House of Aberdeen. His mother was a daughter of the late Sir George Cornewall, M.P. He was born in the year 1811, and succeeded to his father's title in 1823. He was for many years a clerk in the Treasury, and acted as private secretary to at least one Chancellor of the Exchequer. He became a senior clerk in the Treasury in 1854, and a Commissioner of Inland Revenue in 1856; he was also Assistant Gentleman Usher of the Privy Chamber to Her Majesty. Lady Duff-Gordon herself will be better remembered by our readers under her maiden name Miss Lucy Austin, as the author of several clever and entertaining works, including The French in Algiers, and as the translator of Moltke's Russian Campaign on the Danube, and of Rankes' Ferdinand and Maximilian. The title passes to the late baronet's only son Maurice, who was born in the year 1849.
