Sir James 'The Good' Douglas' son William succeeded to the title as Lord of Douglas but may not have completed his title to the estates, possibly because he might have been underage. He died at Halidon Hill with his uncle, Sir Archibald Douglas. James' younger brother, Hugh the Dull, Lord of Douglas, a canon serving the See of Glasgow and held a prebendary at Roxburgh became Lord Douglas in 1342; Hugh of Douglas resigned his title to his nephew, the youngest surviving son of the Regent Archibald, William Lord of Douglas who was to become the first Earl. The First Earl's legitimate son James Douglas, 2nd Earl of Douglas succeeded him. His illegitimate son by Margaret Stewart, 4th Countess of Angus was George Douglas, 1st Earl of Angus, who was the progenitor of the Earls of Angus also known as the "Red Douglases".
