William Cavendish, the 5th Duke of Devonshire (1748-1811), was a British nobleman and politician. He declined three offers to join the Cabinet but served as Lord High Treasurer of Ireland and Governor of Cork. In 1782, he became a Knight of the Order of the Garter. He is best known for his marriage to Georgiana Spencer, Duchess of Devonshire. They had one son and two daughters who left descendants; their title fell into abeyance between them. The dukedom would eventually pass to a grandson from another lineage in the family tree. The fifth Duke also had several affairs resulting in illegitimate children, some who held important positions within society or military service later on.
