Dear Mr. Torraca,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series Administrative and Operational Correspondence Relating to Maine, 1935 - 1944 in the Records of the Work Project Administration (Record Group RG 69) that may include aspects of the Appalachian Trail project. For more information, please contact National Archives at College Park - Textual Reference (RDT2) at Archives2reference@nara.gov.
We also suggest that you request a copy of his Official Personnel File (OPF). OPFs for individuals who worked for the U.S. government in a civilian capacity before 1952 are in the custody of the National Archives at St. Louis (RL-SL). Please email RL-SL via email at firstname.lastname@example.org and include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of the employing Federal agency, beginning and ending dates of Federal Service. For more information, please check the Official Personnel Folders (OPF), Archival Holdings and Access website.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2 and RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
