I have just added elsewhere, after all this time, and will do so here too, that I am wondering whether an entry in the 1841 census under BURTON should in fact read Newton. The original is so faint you just cannot be sure.
Burton William 30 Boats.......
Burton Ellen 25 ..................... Staffordshire
Burton Elizabeth 6
Burton Lucy 1 month Staffordshire
the address is Wharf Street, Stoke upon Trent, Shelton.
If this is the family I was looking for, it takes away the queries about was this the second marriage for Ellen etc, and makes things look far more straightforward. The fact that William and Elizabeth were not born in Staffs fits in too, since I know they were both born in Northants.
