George Douglas, 1st Earl of Angus

George Douglas, 1st Earl of Angus (1380–1403) was a Scottish nobleman and peer.

He was born at Tantallon Castle, East Lothian, Scotland. He was the bastard son of William Douglas, 1st Earl of Douglas and Margaret Stewart, Dowager Countess of Mar & Countess of Angus and Lady Abernethy in her own right.

He was seen as the product of incest as his mother was the widow of Earl William's wife's brother, Thomas, 13th Earl of Mar.

Earl William's wife Margaret of Mar had already produced an heir for her Lord in 1358, James, 2nd Earl of Douglas and Mar inherited upon his father's death in 1384.

In 1389, Margaret of Angus relinquished her title in favour of her son, but he did not assume it until his betrothal in 1397 to the princess Mary, daughter of King Robert III. Margaret of Angus' influence must have been considerable - in addition to obtaining a royal bride for her illegitimate son, she persuaded King Robert to confirm him in his style of Earl of Angus, and also to bestow upon him the lordships of Abernethy, (Perthshire) and Bonkill, (Berwickshire); and "to endow him and his spouse with the justiciary fees of the County of Forfar, to ratify all gifts, entails, and leases made or to be made by Isabel, Countess of Mar, to the said Jorge her brothir" -(Maxwell).

James 2nd Earl of Douglas, was killed without issue in 1388, at the Battle of Otterburn, and the Earldom of Mar, and all non-entailed Douglas possessions passed to his sister Isabel. The earldom of Douglas passed to a cousin, a bastard son of The Good Sir James Douglas, the aptly named Archibald the Grim.
