Percy, Algernon, 6th Duke of Northumberland (1810 -1899)
Algernon Percy was the eldest son of George Percy, Lord Lovaine, and Louisa, daughter of the Hon. James Stuart-Wortley-Mackenzie, second son of Prime Minister John Stuart, 3rd Earl of Bute. From his father's succession as 2nd Earl of Beverley in 1830, Percy was styled Lord Lovaine. In 1865, Lord Beverley inherited the dukedom of Northumberland from his first cousin, Algernon Percy, 4th Duke of Northumberland, and was henceforth styled Earl Percy. Algernon married Louisa, daughter of Henry Drummond, in 1845 (d. 1890). He represented Bere Alston in Parliament between 1831 and 1832, and Northumberland North between 1852 and 1867. He served Civil Lord of the Admiralty between 1858 and 1859 and as Paymaster-General and Vice-President of the Board of Trade in 1859 in Lord Derby's second government. That same year he was also sworn to the Privy Council. In 1867 he succeeded in the dukedom on the death of his father and entered the House of Lords. He joined the Earl of Beaconsfield's second government as Lord Privy Seal in 1878, with a seat in the cabinet, a post he held until the fall of the government in 1880. He was also Lord Lieutenant of Northumberland between 1877 and 1899. He was made a Knight of the Garter in 1886. Northumberland died in January 1899, aged 88. He was succeeded in the dukedom by his eldest son, Henry, Earl Percy.
