Cavendish, Henry, 2nd Duke of Newcastle (1630 -1691)
Henry Cavendish was the fourth and youngest, but eldest surviving, son of Sir William Cavendish and Elizabeth, daughter and heir of William Bassett, of Blore in Staffordshire. His grandmother was Catherine Ogle, daughter and heir of Cuthbert, Baron Ogle, and heiress to the Barony of Bertram. He was Member of Parliament for Derbyshire in 1660, and for Northumberland 1661 1676, and was Master of the Robes 1660 1662, Gentleman of the Bedchamber 1662 1685, Captain of a troop of Horse in June 1666, and Colonel of a Regiment of Foot in 1667, 1673, and 1688. Styled Viscount Mansfield, he succeeded to the dukedom in 1677, and was made a Knight of the Garter the same year. At the accession of William and Mary he refused to take the oaths and retired from all office. He married, in or before 1652, Frances, daughter of William Pierrepont, second son of the 1st Earl of Kingston. They had five daughters but no surviving son, and all his honours became extinct at his death, except the Barony of Ogle. The libraries of William Cavendish, 1st Duke, Henry Cavendish, 2nd Duke, and John Holles, 3rd Duke were sold, at fixed price, by N. Noel, Pater Noster Row 2 March 1719.
