Notes for Sir William DOUGLAS 1st Of Nithsdale
Archibald, third Earl of Douglas, had also a natural son, William, known as Lord of Nithsdale, who seems to have largely inherited the characteristics of his grandfather, Sir James, and whose career, as told by the historians of the time, reads like a romance.

- It is probably he, who as William Douglas of Scotland, is mentioned in the English records in 1372 as having a dispute about the marches with Henry, Lord Percy, though he is not named in Scottish record before 1384.
- In 1385, when the Scoto-French army beset Carlisle, he is said to have performed prodigies of valour.
- In 1388, he made a descent on ireland in retaliation for raids made by the Irish on Galloway.
- On his return, he ravaged the Isle of Man, and landed in Scotland again in time to join his father and the other leaders who invaded Cumberland.
- In the same year, he received from his father a charter of the lands of Harbertshire, co. Sterling.

He is said by Bower to have gone in 1389 to Dantzic, in Prussia, with a number of other Scottish knights, and there to have been assassinated at the instance of an Englishman, Lord Clifford, with whom he had a quarrel. But the story of his alleged murder is a doubtful one, especially as the only ‘Lord Clifford’ known, Sir Thomas Clifford, died between July and November 1391, while Sir William Douglas was alive, if not actually in Scotland, at Martinmas 1390, and seems to have drawn his share of the burgh rents of Dumfries for a good part of 1392.

He therefore probably died in that year [1392], thus surviving his alleged assassin.

Sir William Douglas of Nithsdale married about 1387, Egidia Stewart, a daughter of King Robert II, and said to have been one of the most beautiful women of her time. No record of her appears after 1388, and it is not known when she died.
