This is a long shot, but if you could actually determine where the photo was taken it might help. Try looking up any addresses you have for the family about the right time and then do a search for them. If the roads still exist then there should be pictures on-line which you could compare to the photo (even if they don't still exist there may be archived pictures.) As I say, a very long shot but it could just help.
