Dear Ms. Stauffer,
Thank you for posting your request on History Hub!
We searched the National Archives Access to Archival Databases (AAD) and located the database for World War II Army Enlistment Records but were unable to locate an Army enlistment record for John Lescinski.
To seek the records of John Lescinski, please begin by requesting a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for those who served in the U.S. Armed Forces and who were separated from the service prior to 1956 are in the custody of NARA’s National Personnel Records Center in St. Louis. In many cases where Army and Army Air Corps personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Navy and Marine Corps OMPFs were not affected by the fire. Please complete a GSA Standard Form 180 and mail it to NARA’s National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002.
We searched Ancestry and located All Military Results for a John Lescinski. There may be a fee for using Ancestry to access digitized records. However, you may view these records online at one of NARA's facilities for free via a NARA PC. For the nearest NARA location, please consult our web page at https://www.archives.gov/locations/.
We hope this is helpful. Best of luck with your family research!
