Through marriage she belonged to the Villiers family. She was born Frances Twysden, in London, second and posthumous daughter of The Rt Rev. Dr Philip Twysden (c.1714–52), Church of Ireland Lord Bishop of Raphoe (1746–1752; died 2 November 1752, allegedly shot while attempting to rob a stagecoach near London),
