 Surrey suggested that his sister Mary FitzRoy, Duchess of Richmond and Somerset (widow of Henry's illegitimate son Henry Fitzroy) should seduce the aged King, her father-in-law, and become his mistress, to "wield as much influence on him as Madame d'Etampes doth about the French King".The Duchess, outraged, said she would "cut her own throat" rather than "consent to such villainy".She and her brother fell out, and she later laid testimony against Surrey that helped lead to his trial and execution for treason.
