Delaware, County Naturalization Records - FamilySearch Historical Records

What is in This Collection?
This collection contains Superior Court naturalization records for Kent, New Castle and Sussex counties. The record content and time period vary by county.

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.

How Do I Search This Collection?
Before searching this collection, it is helpful to know: If you do not know this information, check the 1900 census and then calculate the possible year of naturalization based on the date of immigration. The 1920 census may tell you the exact year of immigration or naturalization. If your ancestor naturalized befor 1900, check the census records to see when he or she first appeared in the census. This will give you a 10 year window in which they may have immigrated.
 * The name of the individual
 * The approximate date of naturalization

I Found the Person I Was Looking For, What Now?
You can use naturalization records to:
 * Add any new information to your records
 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * 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
