Charles Campbell Ridgway was a pupil at Lockers Park School, Hemel Hempstead, in 1915. Following a query from Alan, who is related to him, I have added Charles' obituary from the Times. See Ephemera - an empty envelope.
Thanks to information received from Christine I have placed a link to the Chidwickbury Stud on the Childwickbury page.
I have had two queries about photographs taken by Thomas Latchmore of Hitchin, relating to people in the pictures. In neither case was there sufficient clues to be able to identify the individuals. (The more dateable examples of work by Hertfordshire photographs the more I can help people date their old pictures.)
