Tracing Immigrants Country of Origin Records
See Coming to America: Finding Your Immigrant Ancestors in the FamilySearch Learning Center.
You will generally be more successful in learning an immigrant's place of origin with records of the country of arrival. However, some researchers do find the immigrant's hometown in country-of-origin records, especially for uncommon surnames in countries with nationwide indexes or where adequate emigration lists exist. Generally you must know at least the country the emigrant left before you can begin searching these records. If nothing else, you should be able to find that information in country-of-arrival records. In a few cases, you may be able to begin if you know only that the emigrant came from Europe, Scandinavia, or Great Britain. However, get as much information as possible from country-of-arrival records.
