Henry Cavendish, Earl of Ogle
Henry Cavendish, Earl of Ogle (1659 – 1 November 1680), was the only son and heir of Henry Cavendish, 2nd Duke of Newcastle, but died before his father at the age of 21; the Dukedom became extinct on his father's death, but was revived for Henry's brother-in-law: John Holles, Duke of Newcastle-upon-Tyne.
Henry, Earl of Ogle, is remembered mainly for his short-lived marriage to Lady Elizabeth Percy, daughter of the last Earl of Northumberland and the greatest heiress of her time;[1] she was only twelve when they married and was widowed a year later. Her second marriage to Thomas Thynne was a cause of great scandal when he was killed in a duel with her reputed lover. She quickly remarried Charles Seymour, 6th Duke of Somerset: as the Duchess of Somerset became notable for her influence over Queen Anne, and under the nickname "Carrots" was the subject of a violent attack by Jonathan Swift.[1]
