Dear Mr. Wyrick,
Thank you for posting your request on History Hub!
We suggest that you request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and prior to 1958 are in the custody of NARA's National Personnel Records Center in St. Louis. In many cases where 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. 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. If there is any information requested by the SF-180 that you do not know, you may leave that space blank, or provide estimates (such as writing “World War I” for dates of service). However, the more information you provide, the easier it will be for NPRC staff to locate the correct files. You also may attach a letter with any additional information you may have about his service, such as the names of units he was assigned to. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Due to the coronavirus public health emergency, 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.
We searched the National Archives Catalog and located Lists of Outgoing Passengers, 1917 - 1938 in the Records of the Office of the Quartermaster General (Record Group 92) that includes a William W. Wyrick of Soper, Oklahoma; Serial Number 3657430; Company K, 135th Infantry Regiment, 34th Division on the digitized listing (see the record below). His name is crossed off with a notation that he was transferred to the 34th Division Casual Detachment per War Department General Order Number 64, July 1918. We were unable to locate his name on other lists of outgoing passengers. We also searched Lists of Incoming Passengers, 1917 - 1938 in Record Group 92 but were unable to locate his name on the listing.
We searched online and located a copy of War Department General Order Number 64, July 1918. Pages 3 through 4 indicates that persons absent at the time of embarkation would be assigned to casual detachments.
The incoming and outgoing passenger lists are available through Ancestry.com as the data collection U.S., Army Transport Service, Passenger Lists, 1910-1939. Ancestry also has the data collection U.S., World War II Draft Registration Cards, 1942. This database is an indexed collection of the draft cards from the Fourth Registration, often referred to as the "old man's registration." William Wyrick’s registration card in this collection records his birth date as 24 August 1892. 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 Free At-Home Education Resources From Ancestry® and Access to Nearly 500M National Archives Records.
We also searched online and located the unit history Twelfth U.S. Infantry, 1798-1919 that lists him as a member of Company A, 12th Infantry Regiment.
In addition, we located Records of Divisions, 1917 - 1920 in the Records of the American Expeditionary Forces (World War I) (Record Group 120) that includes files of the 34th Division and its subordinate units, to include files on casual detachments. Plus, we located the Records of the 1st Through 338th and the 559th Infantry Regiment, 1916-1921 in the Records of U.S. Regular Army Mobile Units (Record Group 391) that includes records of the 12th Infantry Regiment and the 135th Infantry Regiment. For access to and/or copies of these files, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
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. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your family research!
