Dear Mr. Harrison,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located a series titled Historical Records, 1918 - 1919 in the Records of the American Expeditionary Forces (World War I) (Record Group 120) that includes records of the 148th Infantry Regiment, 37th Infantry Division. We were unable to locate specific records of Company G. Records of lower echelon units sometimes were incorporated into the files of the regiment. We also located a series titled Records of the 1st Through 338th and the 559th Infantry Regiment, 1/1/1916 - 12/31/1921 in the Records of U.S. Regular Army Mobile Units (Record Group 391) that includes records of the 148th Infantry Regiment and its companies. For access to these records, please contact the National Archives at College Park - Textual Reference (RDT2) via email at firstname.lastname@example.org.
We were unable to locate records of Company C. 112th Supply in either Record Groups 120 or 391.
We hope this information is helpful. Best of luck with your family research!
