Thank you all for your continued help with this, I have just logged on this morning.
So we have:
1932: caroline Millard applied for freehold of 202
1936: my cousin’s birth was registered and the address given as his birth in summer of 1935 was 202
1939: no mention of number 202 in that road
1940: a tiler lives at 202.
I’m not sure where to go from here. Did his mother make up an address that did not exist as his birth place perhaps?
