19. Princess Margaret Had Her Own Health Problems
Though not nearly as sick as her brother, Margaret had her own health problems that she had to contend with. Many hoped that she would produce an heir to the throne, but she was unable to have any children. She had two miscarriages and, though she did give birth to six children, only one survived infancy. He would become the Dauphin of France, not the King of Spain. Margaret died during her seventh pregnancy.
