We moved into hasbury road around 1950, where the shops were was all open field land. I would have been around 5/6 when the building started so I would say that your earlier estimate as about right 1956ish. I remember the back land and I would walk across it to visit my friend smithy who lived in woodgate lane. no I did not know the williamsons, most mates were real working class with no-one owning a car even. I remember the dairy facing our house in adams hill. I remember half way up adams hill on the RHS walking towards woodgate was a farm house and next to it a path which ran down to a brook, I was in the scouts which met at woodgate school and marched with them in the 1957 jamboree at sutton park, I am sadly not able to remember anyone else now, I had friends in the prefabs facing the cock inn, I went first to st michaels in the village victorian school then to the new school in field lane/scotland road. you could walk across open field land all the way to the bluebell woods from hasbury road, our doctors was at the top of romsey road near the traffic island, mr gurney the village vicar of st michaels and all angels, and you could walk across the fields from offmore road to field lane too. sorry can't remember much else really.
