 * Place of naturalization

Search by Name by visiting the Collection Page: To search the collection by name fill in your ancestor’s name in the initial search page. This search will return a list of possible matches.

Search the collection by image comparing the information with what you already know about your ancestors to determine which one is your ancestor.

Be aware that with either search you may need to compare the information about more than one person to make this determination.

As you are searching it is helpful to know such information as your ancestor’s given name and surname, some identifying information such as residence and age, and family relationships. Remember that there may be more than one person in the records with the same name as your ancestor and that your ancestor may have used nicknames or different names at different times.


 * If your ancestor used an alias or a nickname, be sure to check for those alternate names.
 * Even though these indexes are very accurate they may still contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.

Use the information in this collection to locate your ancestor's actual naturalization records. You can then use those 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

I Can't Find Who I'm Looking for, What Now?

 * Check for variant spellings of the names and for nicknames.
 * Try a different index if there is one for the years needed. You may also need to search the naturalization records year by year.
 * Search the indexes of nearby localities.

General Tips about Naturalization Records

 * Immigrants could naturalize in any court that performed naturalizations. That included city, county, state and federal courts. Begin by looking for naturalization records in the courts of the county or city where the immigrant lived.
 * Look first 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.
 * Because immigrants were allowed to naturalize in any court, they often selected the most convenient court. If they worked somewhere other than their residence, they may have gone to a court closer to work to naturalize.
 * 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.
