How to Use the Record
The index is arranged according to the soundex system. In the soundex system, surnames are grouped together by sound and given a code. The names within the same code are then arrangen alphabetically by first name. For more information on the soundex, see the wiki article Soundex

Begin your search by coding your surname according to the soundex code. Then find the names in the index. Name indexes make it possible to access a specific record quickly. Check the index for the surname and then the given name. You may need to look at many cards to find the one you are seeking. Remember that these indexes may contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.

When searching the index 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 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.

Use the locator information found in the index (such as name of court, page, entry, or certificate number) to locate your ancestors in the records. Compare the information in the record to what you already know about your ancestors to determine if this is the correct person. You may need to compare the information of more than one person to make this determination.

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:

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. You may also need to search the naturalization records year by year.
 * Search the indexes of nearby counties.
