I'm trying to find out some of my family history. I had a great grandfather in the British army during WWI but my family really don't give a s*** and don't know what regiment he was in, where he served or when he joined but I know he was mentioned in despatches but he has a very common name (Smith!). Even more harmful to my mental health is thought of researching my other great grandfather in WWI who was Polish but became a guardsman in the Austro-Hungarian army. As that empire no longer exists I don't have a clue about where to start! PLEASE HELP!!
