Montagu Douglas Scott, or simply Scott, is the surname of an aristocratic family in the United Kingdom, founded initially in the 15th century as Clan Scott. In the 17th century, James Scott, 1st Duke of Monmouth, eldest illegitimate son of Charles II, King of England, Scotland and Ireland, who would lead the Monmouth Rebellion married Anne Scott, 1st Duchess of Buccleuch. The family name was briefly Montagu-Scott, before the 5th Duke adopted its current form. It is one of only a handful of families in the English-speaking world to have an unhyphenated triple-barrelled name.
The 7th Duke of Buccleuch had a daughter, Alice, who married Prince Henry, Duke of Gloucester (third son of King George V and uncle of Queen Elizabeth II) in 1935, becoming a member of the British Royal Family. Prince Richard, Duke of Gloucester and Prince William of Gloucester are grandsons of the 7th Duke of Buccleuch. Sarah, Duchess of York, former wife of Prince Andrew, Duke of York, is a great-great-granddaughter of the 6th Duke of Buccleuch.
