My name is Andrzej Skowyra. I am a polish citizen. My grandmother's brother Paul Skowyra\ Skowiera was a soldier in the U.S. Army during WW1. Thanks to the archives in St.Louis, I found Paul"s personal file and managed to find his grave in Wyandotte near Detroit. But there are still a lot of questions and mysteries about Paul, so I want to get Paul's retirement file to get as much information as possible about Paul's family and relatives. How can this be done and what resources can be used?
