Dear Ms. Craigmile,
Thank you for contacting History Hub!
The National Archives has an online name index to inmate case files from Leavenworth. It covers the years 1895-1931. Although it does not cover the year 1940, it may be worth it just to check anyway.
Additionally, Ancestry has a name index for inmate case files from Leavenworth. It covers the years 1895-1936. Again, it does not cover the year 1940, but it may be worth it just to check anyway. Ancestry is available to search for free at any National Archives location including regional facilities and presidential libraries. For a location near you, please visit https://www.archives.gov/locations.
For more information on what you might find in an inmate case file from Leavenworth, we suggest reading an article published by the National Archives in Prologue magazine.
Best of luck in your research!
