Margaret Stewart

See also Margaret Stewart. Margaret Stewart (born c. 1455/1456 - c. 1480/1500?) was the younger daughter of James II of Scotland and Mary of Guelders. Once engaged to the Lancastrian Prince of Wales, Margaret instead became the mistress of William Crichton, 3rd Lord Crichton (an enemy of her brother, James III), and the mother of his illegitimate daughter, Margaret Crichton, later Countess of Rothes, and possibly his son, Sir James Crichton, progenitor of the Viscounts of Frendraught. Margaret and Lord Crichton may have been married later, after the death of Crichton's wife. Family Margaret was born between 1453 and 1460, the daughter of James II of Scotland and Mary of Guelders. She had five siblings, including James III, who ascended the Scottish throne in 1460 upon their father's accidental death by an exploding cannon.
