Dear Mr. O Rourke,
Thank you for posting your request on History Hub!
The Federal Government does not ordinarily create or maintain birth, death, marriage or divorce records. Such records are made and kept by State and local governments rather than the National Archives. To locate death records prior to 1925, we suggest you contact the Massachusetts Archives, and from 1926 to the present, contact the Massachusetts Registry of Vital Records and Statistics.
In addition, we suggest that you request a copy of his Official Personnel File (OPF). OPFs and medical information for individuals who worked for the U.S. Navy in a civilian capacity prior to 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, the web site is https://www.archives.gov/st-louis/opf.
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 RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
