How to Use the Record
Immigrants could naturalize in any court that performed naturalizations including city, county, state and federal courts. As a result they often selected the most convenient court. If they lived in the Eastern District but worked elsewhere, they may have gone to a court closer to work.

To begin, look for naturalization records in the courts of the county or city where the immigrant lived. If the county has an index search it first. Next look for the petition (second papers), because they are usually easier to find in courts near where the immigant eventually settled.

After 1906, the declaration can be filed with the petition as the immigrant was required to submit a copy when he submitted the petition.

Look at the images one by one comparing the information with what you already know about your ancestors to determine which one is your ancestor. You may need to compare the information about more than one person to make this determination.

Using the Information
You can 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

You may also find these tips helpful:


 * Look for the Declaration of Intent soon after the immigrant arrived, and 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.

If you do not find the name you are looking for, try the following:


 * Check for variant spellings. Realize that the indexes may contain inaccuracies, such as altered spellings and misinterpretations.
 * Try a different index if there is one for the years needed. Local historical and genealogical societies often have indexes to local records.
 * Search the indexes and records of nearby counties.
