How Do I Search the Collection?
To begin your search it is helpful to know at least some of the following:


 * The full name of your ancestor
 * The birth date or approximate immigration and naturalization dates

I Can’t Find Who 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 other possible localities or ports of entry like [Port of Entry].
 * 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.
