I, too, have been encouraged to research the houses my family have occupied (in addition to the "normal" pursuit of family history!)
Unfortunately, only the first house my parents had is old enough to be on the 1939 - I lived there until I was 6 - but it will be an interesting tangent to go off onto.
I am also going make a start on the house my grandparents lived in - and they were there in 1939 along with my Dad.
Both houses are still standing, so I can see them on up to date references as well.
