Dear Mr. Bitter,
Thank you for posting your request on History Hub!
Given the location and rank that you provided, Private L.W. Lindgren may have served in the U.S. Marine Corps. We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and medical records of officers and enlisted personnel of the U.S. Marine Corps who were separated from service after 1904 and prior to 1958 are located at NARA's National Personnel Records Center (NPRC), (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. To request these records, please mail a completed GSA Standard Form 180 to NPRC. You can also fax the form to 314-801-9195 OR view the record by visiting the NPRC Archival Research Room in St. Louis, MO. You may leave blank any information requested by the form that you do not have. But the more information provided, the easier it will be for NPRC staff to locate the correct file. For more information see Official Military Personnel Files (OMPF), Archival Records Requests
If it is possible to locate an OMPF for him, it may provide additional biographical details about him that can assist in researching him and his family. However, the National Archives does not have the present addresses of former service personnel or their survivors on file. The Federal agency most likely to have such addresses is the Department of Veterans Affairs (VA). The VA can forward a message from you to the veteran, providing the veteran has filed a claim with VA, and they have an address on record. To forward a message, please write your message and place it in an unsealed, stamped envelope. Also include a note to the VA explaining who it is you are trying to reach and add as much identifying information as you have. Place all of this in another envelope addressed to the nearest Veterans Affairs Regional Office (you can find the address at https://www.va.gov/directory/guide/home.asp). If the veteran is in their records, your message to the veteran will be sealed and the envelope addressed to the address they have on file for the veteran. Please note that the veteran may not have informed the VA of a change of address, so they cannot guarantee receipt of your message. If the veteran receives your note, it is then up to the veteran to contact you.
In regards to Chaplain W. Wyeth Willard, if this is Warren Wyeth Willard, we were able to locate a number of sources about him online, including an entry in Social Networks and Archival Context and an obituary in Brown Alumni Magazine which provides a P.O. Box for his daughter (which may not be current) and references a number of organizations he was associated with which may be able to get in touch with his family on your behalf.
If you are certain that he was William Wyeth Willard, he may be another Navy Chaplain. We suggest that you request a copy of his OMPF as well. OMPFs and individual medical reports of officers of the U.S. Navy who were separated from service after 1902 and prior to 1958 are located at NARA's National Personnel Records Center (NPRC), (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. To request these records, please mail another completed GSA Standard Form 180 to NPRC. You can also fax the form to 314-801-9195 OR view the record by visiting the NPRC Archival Research Room in St. Louis, MO.
We hope this information is helpful.
Jason, thank you so much! This is very helpful!
