I recently went through the belongings of my father-in-law's family and found a photo of 5 lieutenants from the army staff at Camp Mountain in Mountain, WI. The 5 Lts are listed as: Manning, Harry Ruhe C.O., Bill Stover, Anthony Francona - Med. Officer, and Sanborn.
These are not my relatives, btw. But since I'm going through the same process with photos and no names attached, I thought maybe this could be a help to someone else. A needle in the haystack, but worth the attempt!
