re the address on the Marriage Certificate, that would be the address where the Groom lived ie Robert Henry, not necessarily with his Father. Also I would be wary of that address as maybe this was just used to show that they werent living together before marriage! He may have genuinely lived next door but think it might have been to cover up they were living together and he may have asked neighbour/relative if their address could be used. Just my theory though.
