Henry VIII and His Six Wives. Janet Hardy-Gould. Ref.416189

There were six of them - three Katherines, two Annes, and a Jane. One of them was the King's wife for twenty-four years, another for only a year and a half. One died, two were divorced, and two were beheaded. It was a dangerous, uncertain life. . Oxford University Press. España. Año 2000. 1ª edición
