Dear Ms. Schepcoff,
Thank you for posting your request on History Hub!
We searched the “Social Security Death Index, 1935-2014” and the “U.S., Department of Veterans Affairs BIRLS Death File, 1850-2014” but were unable to find a listing for him. Death records are typically maintained by the vital records department of the state in which a person dies. Please see the Center for Disease Control’s page on Where to Write for Vital Records.
In regards to his military service, we suggest that you request 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 1958 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. Next of kin can also use eVetRecs to request records. See eVetRecs Help for instructions. If there is any information you do not know, you can leave it blank, however the more information you provide, the easier it will be for NPRC staff to locate the correct file. Proof of death is not required to access records of persons who separated prior to 1958, as these records are open to the general public. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Selective Service records for individuals who served after World War I and were born before 1960 are in the custody of the National Archives at St. Louis (RL-SL), P.O. Box 38757, St. Louis, MO 63138-0757. We located a card that may be a match: James Theo Schepcoff, born 29 August 1913 in Schenectady, New York, USA, and registering 16 October 1940 in Sacramento, California, USA. Please complete Form NA-13172 to request a copy of these records. For more information, see Selective Service Records. These records are also available in digital form and can be viewed online via Ancestry as the data collection U.S. WWII Draft Cards Young Men, 1940-1947
We also searched the National Archives Catalog and located the Muster Rolls and Personnel Diaries of U.S. Navy Ships, Stations, and Other Naval Activities, 1/1/1949 - 12/31/1971 in the Records of the Bureau of Naval Personnel (Record Group 24) that include the muster rolls of the USS Marvel (AM-26). These muster rolls list as a crew member James Theodore Schepcoff, service number 886 91 68, who enlisted in Sacramento, California. He is listed on the muster rolls for 9 June 1944, 19 August 1944, 31 August 1944, 16 Jan 1945, 31 March 1945, and 20 May 1945. For access to and/or copies of these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org. These records are also available in digital form and can be viewed online via Ancestry as the data collection U.S. World War II Navy Muster Rolls, 1938-1949
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. Also, the National Personnel Records Center is servicing only urgent requests related to homeless veterans, medical emergencies, and funerals which may be faxed to 314-801-0764. We thank you for your patience and look forward to resuming normal operations when the public health emergency has ended.
In response to the COVID-19 pandemic, the National Archives has partnered with Ancestry to make the vast majority of their NARA-digitized holdings freely available to the public. Anyone with Internet access can create an account and access NARA records and use other Ancestry resources, such as their educational offerings and family tree-maker application. For more information see their announcement at https://blogs.ancestry.com/ancestry/2020/03/24/free-at-home-education-resources-from-ancestry-and-access-to-nearly-500m-national-archives-records/
