Who married William Stafford?

Mary Boleyn (c. 1499 – 19 or 30 July 1543), also known as Lady Mary, was the sister of English queen consort Anne Boleyn, whose family enjoyed considerable influence during the reign of King Henry VIII.

Mary was one of the mistresses of Henry VIII for an unknown period. It has been rumoured that she bore two of the King's children, though Henry did not acknowledge either. Mary was also rumoured to have been a mistress of Henry VIII's rival, King Francis I of France, for some period between 1515 and 1519.

Mary Boleyn was married twice: in 1520 to William Carey, and again, secretly, in 1534, to William Stafford, a soldier from a good family but with few prospects. This secret marriage to a man considered beneath her station angered King Henry VIII and her sister, Queen Anne, and resulted in Mary's banishment from the royal court. She died seven years later, having spent the remainder of her life in obscurity.
