1851 census shows John Porter, b1798 Keisby, and Mary,b 1799 North Witham. 1881 show Mary, b1797 North Witham, whats two years on a census? I cannot find any Keisby details on IGI. Please can anyone look up JP's birth?,and their marriage, first child born 1820, North Witham. I cannot find any North Witham marriages, but have found 3 possible Marys christened. Thank You MIK.
