I M Looking for Information on Lot Watson and His Family

I am interested in finding information on Lot WATSON born c1809 in or near Barkway, Hertfordshire, England andhis family. Lot appears to have always lived in the Barkway area. He was a bricklayer and may have been married several times. He had 2 sons. Thomas born c1832 was also a bricklayer and married Maria (surname not known) and John born cJan 1835. John was a butcher and baker. He married Anne LAWRANCE 29 Nov 1856 in Braughing. He appears to have moved to Essex between 1851 and 1861.
I would be grateful for any help or suggestions anyone has on this family.
