I am William Cavendish, 5th Duke of Devonshire, I was a British nobleman, aristocrat, and politician. I was the eldest son of William Cavendish, 4th Duke of Devonshire, by my wife, the heiress Lady Charlotte Boyle, suo jure Baroness Clifford, who brought in considerable money and estates to the Cavendish family. I was invited to join the Cabinet on three occasions, but declined each offer. I was Lord High Treasurer of Ireland and Governor of Cork, and Lord Lieutenant of Derbyshire. In 1782, I was made a Knight of the Order of the Garter.
