Elizabeth Woodville (Elizabeth Wydeville, Elizabeth Widvile) (c. 1437 – 8 June 1492) was Queen consort of Edward IV, King of England, from 1464 until his death in 1483. Elizabeth was a key figure in the series of dynastic civil wars known as the Wars of the Roses. Her first husband, Sir John Grey of Groby was killed at the Second Battle of St Albans. As the daughter of Richard Woodville, 1st Earl Rivers, she was the first commoner to marry an English sovereign. It was because of this that Edward's former staunch ally Richard Neville, 16th Earl of Warwick, known to history as "The Kingmaker" switched his allegiance to the House of Lancaster. Her children included the Princes in the Tower and Elizabeth of York; the latter made her the maternal grandmother of Henry VIII.3147
