John Stewart, Earl of Mar (December 147911 March 1503) was the youngest son of James III of Scotland and Margaret of Denmark.[1]
He was born at Dunfermline Palace in Fife as the youngest son of the King. He was created Earl of Mar on 2 March 1486, at the age of eight. Not much is known of his life and he died on 11 March 1503.[2]
As he died unmarried, the earldom became extinct for almost 60 years, and James IV awarded many of the Mar lands to Lord Elphinstone.[3]
Stewart had two brothers, King James IV and James Stewart, Duke of Ross.
