Vernon Henry St John, 6th Viscount Bolingbroke (1896–1974) was the fourth child of the 5th Viscount and his wife Mary Elizabeth Emily, a former domestic. The couple's secret marriage and the existence of an heir was revealed only after the death of the 5th Viscount in 1899. It came as a huge shock to the locals and went on to become a national scandal. Although the couple had three boys, Vernon Henry was the only one who was legitimate and thus inherited the title of Viscount Bolingbroke.
