Washington, County Naturalization Records - FamilySearch Historical Records

What is in This Collection?
The records include petitions, declarations of intention, certificates, depositions and final papers. The records are arranged chronologically. Naturalization is the process of granting citizenship privileges and responsibilities to foreign-born residents. Counties recorded naturalization procedures in the court records as legal proof of citizenship. 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.

The 1920 census may tell you the exact year of immigration or naturalization.

 * The birth date or place of your ancestor
 * The approximate immigration and naturalization dates

I Found the Person I Was Looking For, What Now?

 * Add any new information to your records
 * Use the information found in the record to find other records such as emigrations, port records, and ship’s manifests
 * Use the record to learn your ancestor’s foreign and “Americanized” names, if they were different
 * Use the record to learn the place of origin then search there for church or vital records such as birth, baptism, death, and marriage records
 * Search this collection for other family members who may have immigrated with the person you are looking for
 * Search for additional family members in census records
 * 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, 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

I Can’t Find the Person I’m Looking For, What Now?

 * If your ancestor does not have a common name, collect entries for every person who has the same surname. This list can help you find possible relatives
 * If you cannot locate your ancestor in the locality in which you believe they lived, then try searching in other locations
 * Try different spellings of your ancestor’s name
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names
