Is he alive when the census was taken? If so was he born in the same county or not. If so you can look for a baptism starting with the same parish he married in.
A clue could be his childrens names, often people named their children after their father/father in law and mother/mother in law.
None of this is 'proof' of parents but does give you some clues
