Dear Ms. McNamara,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the series titled Draft Registration Cards, 1917-1918 in the Records of the Selective Service System (World War I) (Record Group 163) that may include a card for your relative. For copies of these records, please contact the National Archives at Atlanta (RE-AT) via email at firstname.lastname@example.org.
Please note that the National Archives and Records Administration (NARA) has suspended reproduction and digitization services until further notice due to COVID-19. Orders will not be serviced until operations can resume safely. Once operations resume, document reproduction requests will be filled in the order in which they were received. We apologize for any inconvenience.
We hope this is helpful. Best of luck with your family research!
