So , we have found HAnnah's maiden name, and we've found George's death. All we have failed on is a photo of the dairy (assuming he had a dairy, and didn't just keep cows for some else, and trade in hay etc aswell)
Did you look at googlemaps? Unless the road has been re-numbered, no 8 is a terraced house, but next door is numbered 8a, so maybe it used to be a larger house now divided?
Opposite on the other side of the road are garages - maybe that was fields in the days before everyone had a car, and thus was where the cows grazed, or maybe barns etc for hay storage.
