How to Use the Record
To begin your search it is helpful to know the following:


 * The full name of your ancestor
 * The approximate immigration and naturalization dates
 * The ancestor’s residence

If you do not know this information, check the 1900 or 1910 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.

Search the Collection
To search the collection: ⇒ Select "Browse through images" on the initial collection page ⇒ Select the appropriate "County" ⇒ Select the appropriate "Register, Year Range, and Volume" which takes you to the images.

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
When you have located your ancestor’s record, carefully evaluate each piece of information given. These pieces of information may give you new biographical details that can lead you to other records about your ancestors. Add this new information to your records of each family. For example, 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.

Tips to Keep in Mind

 * 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.

Unable to Find Your Ancestor?

 * Check for variant spellings of the names.
 * Look for an index. There are often indexes at the beginning of each volume. Local genealogical and historical societies often have indexes to local records.
 * Search the indexes and records of nearby counties.
