So I'm doing my family tree on ancestry, pretty productive and up to about 900 people and still ploughing through! Have found a living second cousin I didn't know I had 
I really want to find a relatives war records but it's proving elusive. I have his full DOB, name, parents etc and I know he was a POW and I have his Burma star medal. Any tips? It's a pretty common name. Am happy to share my tree by PM if it helps!
