I was at a workday for the Friends of Walkley Cemetery a couple of weeks ago and was tackling a section of the cemetery that was overgrown - see photo
In this section I uncovered a memorial that was in remarkable condition for its age
And at the base of the memorial was this dedication to James and Caroline's grandson Clifford who was killed in action on 8th May 1915
