Ohio, County Naturalization Records - FamilySearch Historical Records

What is in This Collection?
The collection consists of images to naturalization records from county courthouses in Ohio for the years 1800 to 1977. The record content and time period varies by county. Some counties have indexes that cover years later than 1954.

Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. The first naturalization act was passed in 1802. Immigrants to the United States were not required to apply for citizenship. Of those who did apply, many did not complete the requirements for citizenship.

Naturalization to become a U.S. citizen was a two-part process: the Declaration of Intent to Naturalize, or First Papers, and the Naturalization Record (including the Naturalization Petition), or Final Papers. The First Papers were normally filed five years before the Final Papers because of the five-year residency requirement to become a citizen.

No centralized files existed before 1906. In 1906 federal forms replaced the various formats that had been used by the various courts. Copies were sent to the Immigration and Naturalization Service (INS), creating a central file for naturalization papers. The INS is now known as the U.S. Citizenship and Immigration Services (USCIS).

Naturalization records are generally well preserved, but some records may have been lost to fire or other disasters.

The information that was current at the time of naturalization was usually reliable. However, there was always a chance for misinformation. Errors may have occurred because of the informant’s lack of knowledge or because of transcription errors or other circumstances.

I Found the Person I Was Looking For, What Now?
Use naturalization records to:


 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * Learn foreign and “Americanized” names
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests
 * Look for the Declaration of Intent soon after the immigrant arrived, then look for the Naturalization Petition five years later when the residency requirement would have been met. Look for naturalization records in federal courts and then in state, county, or city courts
 * An individual may have filed the first and final papers in different courts and sometimes in a different state if the person moved. Immigrants who were younger than 18 when they arrived did not need to file a Declaration of Intent as part of the process
 * If your ancestor had a common name, be sure to look at all the entries for a name before you decide which is correct
 * Continue to search the naturalization records to identify siblings, parents, and other relatives in the same or other generations who may have naturalized in the same area or nearby
 * The witnesses named on naturalization records may have been older relatives of the person in the naturalization process. Search for their naturalizations
 * You may want to obtain the naturalization records of every person who shares your ancestor’s surname if they lived in the same county or nearby. You may not know how or if they are related, but the information could lead you to more information about your own ancestors
