Margaret Tudor (29 November, 1489 - October 1541) was the eldest of the two surviving daughters of Henry VII of England and Elizabeth of York, and the elder sister of Henry VIII. In 1503 she married James IV, king of Scotland, thus becoming the mother of James V and grandmother of Mary Queen of Scots. Most important of all, Margaret's marriage to James was to lead directly to the Union of the Crowns. Fate, it was once argued, had intended Margaret to be Queen of Scots. Wikipedia
