Hi Anne,
Stoke is a large sprawling district, and having various parts such as Stoke Aldermoor, Stoke Green, Stoke Heath, etc. makes it awkward to navigate for someone not brought up in the area. The bit we're interested in is probably mostly known as "Middle Stoke", and I've marked a red cross on the map where the 1911 kilns were found and a square for the 1917 finds.
