I have a photograph dating from 1917 (give or take a year) featuring a man who is described but not named.
Facts given in the caption to the photo:
He is the son of Mrs Smith of 208 Southampton Street, Reading.
He worked as a postman for 12 years - some if not all of the time at Newbury.
He served in the Boer War.
He re-enlisted at the start of the war.
He was a prisoner of war in Germany having been captured in September 1914.
So who was he? I have been unable to find a Newbury postman called Smith, but his mother may have remarried.
