"The courtship of Elizabeth Woodville by Henry's grandfather was remarkably similar, though no letters remain. Edward laid out bribes to her father, Richard Woodville, Lord Rivers, and made financial offers to Elizabeth. In the end, he too tried to force the issue. Contemporary stories tell of Edward's reaching the point of putting a knife to Elizabeth's throat and being told that she was `determined to die rather than live unchastely with the King'. Again, only marriage gave him what he wanted."
