The Private Life of Edward IV
From the moment it became public news, the validity of Edward's marriage to Elizabeth Woodville, the beautiful widow of a Lancastrian knight, was repeatedly called in to question. This alarmed Elizabeth Woodville and led her into political killings. She was terrified that she would lose her crown and that her children by the king would never succeed to the throne.
But after Edward's death a bishop publicly announced that he had previously married the king to Lady Eleanor Talbot. As a result, Edward's children by Elizabeth, including his eldest son and heir to the throne, Edward, were then declared illegitimate, making Edward's brother Richard the legitimate heir to the throne. Later, claims were put forward that Edward had numerous mistresses and left behind many illegitimate children.
