Why would they have not named a single resident at an address in the 1939 register?
I know the house was occupied, well at least I have been told that the 'Jones' family were living there at that time - "I lived at 47 Durley Ave Pinner in 1937(aged 2)".
I was just across the road at No.74 from November 1937 when the houses in our Avenue were first built.
Then why the Tick to the left of the address?
The tick is probably a 'V' which denotes a vacant property. It doesn't necessarily mean unoccupied, it could just mean that the occupants were away from home at the time of the enumeration, in which case they should be enumerated wherever they happened to be on the night of 29 September 1939.
