 Thank you for posting on History Hub! 
 Naturalization records dated prior to October 1991 from the federal courts are at the National Archives. If your great-grandmother was naturalized in a federal court before October 1991, you will need to contact the NARA field site that maintains federal court records for the state where he was naturalized. To determine which facility you need, please visit our webpage at www.archives.gov/.../court-records . Please note that no central index to naturalizations exists . 
 If your grandfather remained in Pennsylvania and was naturalized in federal court there, we recommend that you contact the National Archives at Philadelphia. Please note the following links to contact that field site:
