Searching for information about my father, David Campbell born about 1921/1922 probably Kentucky or Tennessee. He served in the Army during WWII and was stationed at Fort Williams, Maine about 1940( most likely in the Coastal Artillery). From there he was transferrred to either Fort Devens, MA or Camp Edwards, MA awaiting overseas assignment to the European Theater. Last known whereabouts during that time was in Italy. Have been searching for a long time and keep hitting that proverbial "brick wall" I know he existed..I have a photo of him in uniform taken shortly after his 18th birthday. What information I have was provided by my biological mother, now deceased, and is sketchy at best. They were not married and she believed he was KIA. I was placed for adoption. I am interested in providing a family/medical history for my children and grandchildren! Is it possible to findwhat unit he actually served in without more info such as serial number, BD and induction location?
