Thanks Susan,
I will try that. They have the book in the library and as I cant take it out I wonder if there is anyone who could take the book out and look up James Lambert and his sons James Halls Lambert and Alfred Lambert and any other Lambert's for that matter. They were brickmakers in Stotfold in the 1851 census and were there in the Biggleswade area until the late 1890's.
Thanks.
