Daughter of Edward IV and Elizabeth Woodville. In 1473 Cecily was betrothed to James the son of James III, King of Scotland in return for peace on the border between England and Scotland. Cecily was only four at the time and the arrangement would have to wait until both she and James were old enough to marry. After the death of her father Edward, Richard III, Cecily's uncle became king of England. Richard had all of Edward and Elizabeth's children declared illegitimate and arranged a marriage for Cecily to a supporter of his, Ralph Scrope. The reign of Richard came to an end after he was killed at the Battle of Bosworth and Henry VII became king. Henry reversed Richard's declaration that Edward's children were illegitimate and had Cecily's marriage to Scrope annulled. He then arranged a marriage for Cecily to John, Lord Welles, a Lancastrian supporter. After the death of Lord Welles, Cecily married, without the permission of the king, Thomas Kyne. After her death in 1504 Cecily was buried at Quarr Abbey on the Isle of Wight.
