Hi Anne,
The only clue I can see is that Joseph BRATT who John is with in 1841 maybe related. Here he is in 1851, HO107 2246/83 Page 24, Castle Street, Wardleworth:
Josh BRATT, Head, Mar, 41, Boiler Maker born Cheshire Hover [Possible OVER]
Mary BRATT, Dau, U, 18, Factory Operative born Manchester
James BRATT, Son, 15, Boiler Maker born St Helens
Josh BRATT, Son, 11, Boiler Maker [dittoed from above] born Royton
I wonder if Joseph is John's brother?
Jean
PS. My Schofield line is in the Oldham/Ashton area of Lancs as far as I have got with them
