I Found Who I Was Looking For, What Now?

 * Use the information to find other records such as emigrations, port records, and ship’s manifests.
 * 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.
 * Learn foreign and “Americanized” names
 * Learn the place of origin and find church and vital records such as birth, baptism, marriage, and death records. Also search for military, land and probate records.
 * Use the information to find additional family members in censuses.
 * Repeat this process with additional family members found, to find more generations of the family.
 * Church Records often were kept years before government records were required and are a good source for finding ancestors before 1900.

I Can’t Find Who I’m Looking For, What Now?

 * Try viewing the original record. Indexes and transcriptions may not include all the data found in the original records. Remember that there may be more than one person in the records with the same name.
 * If your ancestor does not have a common name, collect entries for every person who has the same surname. This list can help you identify possible relatives that can be verified by records.
 * If you cannot locate your ancestor in the locality in which you believe they lived, then try searching records of a nearby locality in an area search.
 * Try variant spellings of your ancestor’s name.
 * Remember that sometimes individuals went by nicknames or alternated between using first and middle names. Try searching for these names as well.
 * Search the indexes and records of Wisconsin, United States Genealogy.
 * Search in the FamilySearch Library Catalog
