Elizabeth Woodville into the most notable families in England. Three of her sisters married the sons of the earls of Kent, Essex and Pembroke. Another sister, Catherine Woodville, married the queen's 11-year-old ward Henry Stafford, 2nd Duke of Buckingham, who later joined Edward IV's brother Richard, Duke of Gloucester, in opposition to the Woodvilles after the death of Edward IV. Elizabeth's 20-year-old brother John married Katherine, Duchess of Norfolk. The Duchess had been widowed three times and was probably in her sixties, which created a scandal at court. Elizabeth's son from her first marriage, Thomas Grey, married Cecily Bonville, 7th Baroness Harington.
Elizabeth Woodville offered the throne and became King Richard III. Edward V, who was no longer king, and his brother Richard, Duke of York, remained in the Tower of London. There are no recorded sightings of them after the summer of 1483. Now referred to as Dame Elizabeth Grey, she and the Duke of Buckingham (a former close ally of Richard III and now probably seeking the throne for himself) now allied themselves with Lady Margaret Stanley (née Beaufort) and espoused the cause of Margaret's son Henry Tudor, a great-great-great-grandson of King Edward III, the closest male heir of the Lancastrian claim
