My great uncle, William Charles Kasdorf was born in Whitman County, near Colfax on August 29,1891 and died in France during WWI. According to a newspaper article I found, he was listed as missing for several months and it required a month to locate his burial place in France. His body was returned to Colfax and his funeral was June 18, 1921, which would make his death sometime in the latter part of 1920. The date on his tombstone is September 8, 1918, which I believe is the date he entered the service. His unit was the 109 Infantry, 34 Division, which I looked up and read that they didn't leave for France until
September 18, 1918.
I would love to have any information the book shows, and I am crossing my fingers that there is a picture of William, or any other Kasdorf that may be in you book.
Thanks so much for sharing this wonderful information.
