Well this is very exciting! I am working on my Narrative Lineage for my BCG certification and was looking through my files for an article on Michael Kokoska where it lists his brothers in the service. I cannot locate the file so I went to ProQuest, Historical Chicago Tribune, looking for the article I and came across articles about WWI Draftees being accepting into the new army! I had no idea the Trib published lists of Draftees and Enlisted men after their examinations. I stumbled upon the first article quite by accident and I’m so excited to have found this!
If you know what Draft Board your Chicago ancestor registered with, you can look through the lists, which say District rather than Draft Board. Michael registered with the draft board 5 June 1917. He is listed in the paper 15 August 1917 as being accepted as physically fit for service. I searched from 6 June 1917 – 1 October 1917 for District 26 and then started reading each entry that popped up. I now plan to do the same for his brothers. I know three of them, from that article I cannot locate at the moment, were either drafted or enlisted and served/trained stateside. The brothers never saw action overseas, only Michael.
What an exciting find!
