Maine Naturalization records online and Maine Citizenship Records online may include declarations of intent, petitions for naturalization, oaths of allegiance, certificates of citizenship, and more.

 

These records often provide names and aliases of a person, age, country of birth, ethnic background, date and port of arrival, the name of the ship, previous residences, or current address.

 

You can look at federal (1870-1920) and state census (1825-1925) records to see if your ancestor was naturalized. See Maine Census Records online for census record links and other helpful sources. Also see Maine Emigration and Immigration Records online.
