This posting is not meant kickstart the Brexit debate here!!!!
This gathering was more likely to have been for those officers based in the wider 'local area' attending a centralised training session at the Grammar School. Most of the villages/towns in the area of south Northumberland (and Nationwide) would have had Home Guard troupes under the command of an officer so I reckon they could be from Morpeth, Ashington, Blyth, and assorted villages.
I'm still thinking this photo is in Vulcan Place, perhaps opposite the pub. If you look at old maps there was no building going on in Vulcan Place until sometime 1870 - 80. The rest of central Bedlington is a great deal older. It's reasonable to believe that stone-working skills had improved from the rough cuts seen in the earlier photos.
Sadie is the diminutive name of the name Sarah. James and Mary, both born 1895 in Bedlington, had a daughter Sarah Jane, born 1914. They had two other children: William George born 1918 and Phyllis born 1919. I think the child in the photo, if she is known as Sadie, is probably Sarah Jane. Could the photo have anything to do with the end of WW1? Early 1920s?
