The IGI lists several interesting possible facts about this man. He is probably the German Campion christened at Mickleover, Derbyshire, England on 30 April 1745 to Robert and Jane (Camm) Campion. He likely married Mary Cockaine 5 Sep 1769 at Mackworth, Derbyshire, England. He may have returned to England following his indenture in America and be the German Campion who married Jane Jones on 27 Aug 1783 at St Mary Magdalen Old Fish Street Parish in London. (2)
