During the First World War, the Aberdare Leader printed photos of local men, and women, who served in the armed forces. Each issue carried such photos along with details of their experiences. Focusing on Mountain Ash and Penrhiwceiber, I have collated some 130 such photos, along with as many articles as I can find relating to those named, amounting to some 23,000 words. A full index is provided via the World War One menu above, or here. As the photos below show, the quality is not good but, in conjunction with the biographical information available, I think they are of interest and value to family and local historians.
