Dear Ms. Wanic,
Thank you for posting your request on History Hub!
Details about parents are not recorded on Declarations of Intentions or Petitions for Naturalization. However, we suggest obtaining a copy of your grandmother’s naturalization records, as they could be useful in identifying where she was born. This information can help you in the search for a birth certificate from her country of origin. Original naturalization records are in the custody of the National Archives at Chicago (RM-CH). For access to and/or copies of these records, please contact RM-CH via email at email@example.com.
We hope this is helpful! Best of luck with your family research!
