Naturalization Records

Dear Ms. Griffin,

Thank you for posting your request on History Hub!

The National Archives could maintain a copy of the Petitions for Naturalization.  If you know which state the individuals resided in, you can contact the field office that maintains records for that state (learn more: https://www.archives.gov/research/naturalization). 

If the naturalizations occurred post-1906, you may also be able to obtain additional records from the naturalization process (i.e. Certificate of Citizenship) by placing a request to the US Citizenship and Immigration Service (USCIS) Genealogy Program (www.uscis.gov/genealogy).

For additional, please check the blog post Immigration and Naturalization Records: Where are they?

We hope this information is helpful. Best of luck with your research!
