I think there might be an intervening generation,as the family you describe is at HO 107 881 21/11 17 in 1841 with children from Sarah down and Joseph next door.
John's birth is given as 1791,but as the ages were rounded(down) generally to the nearest 5,it could be between 1787and 1791.This could leave John(circa 1772) as the father of this John,who would have been between 17 and 24 if he married in 1808-1811.
