Wisconsin County Naturalization Records - FamilySearch Historical Records

Record Description
This collection contains naturalization records from county courthouses in Wisconsin. The record content and time period varies by county.

Record Content
The records usually include the following information:


 * Full name
 * Current residence
 * Birth date and place of birth
 * Date Naturalized
 * Name of court
 * Age when naturalized
 * Spouse's name, married
 * Names of children
 * Arrival date and port of entry
 * Certificate number

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.

Search the Collection
To search the collection you will need to follow this series of links: ⇒Select the "Browse" link in the initial search page ⇒Select the "County" ⇒Select the "Record Type, Year Range, and Volume number" which takes you to the images&lt;

Search the collection by image comparing the information with what you already know about your ancestors to determine if the image relates to them. You may need to look at several images and compare the information about the individuals listed in those images to your ancestors 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.

Using the Information
When you have located your ancestor’s record, carefully evaluate each piece of information given. Save a copy of the image or transcribe the information. These pieces of information may give you new biographical details. Add this new information to your records of each family. You should also look for leads to other records about your ancestors.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. 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.
