Johnson Rule born in 1796 (firm on year); married Elizabeth Jones on 2 Dec 1816 (according to freepages.genealogy.rootsweb.ancestry.com/~camborneopc/marriage1813.htm). I cannot find any other confirmation of this marriage. Based on 1841 and 1851 census data I am firm on 1796 date of birth for Johnson. Wife, Elizabeth, was 5 years older. 1861 census shows place of birth as Illogan. But marriage record shows her as sojourner.
