Hi Nigel: I confirm that the Pte 23868 William REES is my relative. As well as having a photo-card of both William and Dick Jones I can say that the photo was taken in Colwyn Bay in June 1915. I also have a copy of a message written on the postcard dated June 1915 from Dick Jones to a Miss Enid Williams, the young daughter of E A Williams, a dressmaker, who lived on The Avenue, Gwaleodygarth, Merthyr. The postcard was signed 'Uncle Dick'.
Perhaps the above bit of information will help me further to connect to the Jones family and anyone connected like the Williams family.
If I find out anything about your George Richards from the same unit I will let you know. Did George come from Merthyr? I hate these brick walls we are up against - don't you?
Happy New Year.
Helsian
