Hi Trish and Pam
Many thanks for the information - I believe Pury End must be a hamlet, looks much smaller on my map than Paulerspury ! Will have to google and see if I can find any mention of a farm there. I suppose it was a bit much to hope he was still at home at the age of 20!
As a child growing up in the Hamlet, there were several farms. Some guessing by the buildings had been there a long time.
The largest was just off Carey's Road on the west. A small farm ( Home Farm ? ) in the centre of the bottom triangle, this might be more modern, I am not sure. The top of the Hamlet ( North ) was the big house of the hamlet, this too had farm out buildings and there I think was something at Botany Bay which was again on the North side of the hamlet.
Paulerspury nearby has some also, one of the larger is just South of Paulerspury and I think might be called Park Lane Farm. If any ring a bell let me know and I can check the names next time I am up there.
