Yes, that's what I would assume; but, since Andrew subsequently received a pension after 1917 (the Army Invalid pension) I would guess that his file remained "live" and might have been passed along into the St. Louis records.
How can I ask the Washington or St Louis Archive if they have the record?
Dear Mr. Martin,
Thank you for posting your request on History Hub!
Please email both the National Archives at Washington, DC (RDT1) at email@example.com and the National Archives at St. Louis (RL-SL) at firstname.lastname@example.org to inquire about these files. Please attach images of the pension index cards you have located to your request.
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 RDT1 and RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
Also, pension files may be in the custody of the Department of Veterans Affairs if they were still active in 1955 when the inactive files were transferred to the National Archives. Even though he died in 1940, his file may have still been active if there was a surviving dependent collecting benefits. If neither RDT1 nor RL-SL have these files, please file a FOIA request with the Department of Veterans Affairs. Their FOIA website is https://www.va.gov/foia/
We hope this is helpful. Best of luck with your research!
Thank you Jason.
I've been struggling with how to approach this problem for months and your response is a really clear, helpful path. Thanks!
