I have a friend who to say the least has no clue about computers so I told him I would check for info on a photo he has. Hope someone here may be able to help. He has a photo of Co E 303rd ammunition train taken at Camp Dix May 1919. Is there somewhere either He or I could find out the names of the soldiers in this photo? He believes one of them is his grandfather but not sure. His father recently passed and the photo was found among his belongings.
