Hi Gill,
The 1861 records James age 34, baker and Elizabeth 30 living at Damask Green,Weston, with four children, Mary 7, George 5, Thomas 3, and Walter 1. All born in Weston.
James birthplace is shown as Norton, Herts and Elizabeth's as Gt.Morden, Cambridgeshire.
The IGI records two births at Norton circa 1816, George and George Adam Thompson both offspring of William and Sarah Thompson. Did one subsequently assume the name James?
Something to think about.
Regards ... Peter
