I recently acquired a WW1 Trio and some documents to 10014 Pte Frederick Stockham, Father in Law of my next door neighbour. I am trying to find out more about him as he appears to have been a PoW, possibly in Russia. Have attached one of the documents. I also have a copy of the letter signed by King George V, welcoming him home after PoW release. Can anybody please help with some info on him? Much appreciated. Dudley
