Elizabeth Woodville
Dame Elizabeth Grey
United Kingdom
Now referred to as Dame Elizabeth Grey, she, with 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 to the throne with any degree of validity.
