By chance I came across the Llandudno Parish website which has a section devoted to those who fell in the Great War. The very useful section has a biography of each man including details of parentage, where lived and so on. Really interesting and of help to those researching family history. Some folk have gone to a great deal of time and trouble to gather all this information. Worth a look.
