Hi, In Lawson's 1851 census list, John is 28, Ann is 31 (which tallies with 1820 birth) & John is 2. Maybe Ann died in childbirth as Robert (3rd surviving son) was born in the year she died 1845. John didn't take long to remarry Jane & produced his next son Joseph more or less straight away. I wonder if she was Ann Mylrea? Maybe her parents disinherited her because she was almost an unwed mother !
