I Found the Person I Was Looking For, What Now?

 * Make sure to fully transcribe and cite the record entry for future reference; see the section Citing this Collection for assistance. Save or print a copy of the image
 * Use the information found in the record to find other records such as emigrations, port records, and ship’s manifests.
 * Use the record to learn your ancestor’s foreign and “Americanized” names, if they were different.
 * Use the record to learn the place of origin and find their church and vital records such as birth, baptism, and marriage records.
 * Use the information found in the record to find land and probate records.
 * Use the record to see if other family members who may have immigrated with the person you are looking for are listed and have additional information or leads; you may also find additional information on new family members in censuses.
 * Repeat this process with additional family members found, to find more generations of the family.
 * Church Records were kept years before counties began keeping records. They are a good source for finding ancestors before 1900.

I Can't Find the Person I'm Looking For, What Now?

 * If your ancestor does not have a common name, collect entries for every person who has the same surname. This list can help you find possible relatives.
 * If you cannot locate your ancestor in the locality in which you believe they lived, then try searching records of a nearby town or county.
 * Try different 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.
 * Look for the Declaration of Intent soon after the immigrant arrived. Then look for the Naturalization Petition five years later, when the residency requirement would have been met. Look for naturalization records in federal courts, 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.
 * Check other possible ports of entry
