Hi, I've also got a paternal great uncle who emigrated to Patagonia c1919 after getting his future wife pregnant, its not clear whether they were married prior to emigration. He was John Robert Williams of Llangelynnin Conwy and I believe his wife was from the dyserth area in flintshire. I have been trying for some months to find his family as I know he had a daughter Glenys who managed to communicate with my late father during the early seventies, all communication ended with the Falklands war and my parents lost the address, even with this much I'm finding it hard to get anywhere, I hope you have better luck and if you do please contact me with details. Cofion Wendy
