Percy, Henry George, 7th Duke of Northumberland (1846 -1918)
Henry Percy was born 29 May 1846, the eldest son of Algernon Percy, 6th Duke of Northumberland, and Louisa, daughter of Henry Drummond. He became known by the courtesy title Lord Lovaine when his grandfather succeeded in the dukedom of Northumberland in 1865 and as Earl Percy when his father succeeded in the dukedom in 1867. He was Member of Parliament for Northumberland North in 1868, was sworn of the Privy Council in 1874, and appointed Treasurer of the Household under Benjamin Disraeli, a post he held until 1875. From 1879 to 1883 he was Chairman of the National Union of Conservative and Constitutional Associations. The Northumberland North seat was abolished in 1885 and Percy was not elected for another constituency. Two years later he was summoned to the House of Lords through a writ of acceleration in his father's barony of Lovaine. Percy succeeded in the dukedom in 1899 upon his father's death, and was made a Knight of the Garter the same year. He later served as Lord Lieutenant of Northumberland from 1904 until his death in 1918 and was Lord High Steward at King George V's coronation in 1911, where he bore St Edward's Crown. Northumberland married Lady Edith Campbell, daughter of George Campbell, 8th Duke of Argyll, on 23 December 1868. They had thirteen children. He died 4 May 1918, and was succeeded by his son Alan Ian Percy, 8th Duke of Northumberland.
