Immigration, Emigration and Naturalization Research Resources

By Family Tree Editors Premium

Searching for records of your immigrant great-great-grandfather, you may feel as if you’re tossing a lasso at the prize bull but always coming up empty-handed. Rounding up those elusive records will be easier if you know your ancestor’s full original name, age at arrival and date of arrival. Additional facts such as country of origin, names of family members traveling with him, port of departure, port of arrival and ship name will focus your search further.

It also helps to understand the history behind the records you’re hunting. Beginning in 1820, the US government required shipmasters to complete pre-printed passenger lists. Those lists documented each passenger’s name, age, sex, occupation, country of origin and destination. Once the ships arrived on American shores, shipmasters gave the lists to customs collectors at the port and inspectors verified the arriving passengers’ names with those on the lists.

Some of the resources here index lists from various ports and years. You can find passenger lists on microfilm at the National Archives and Records Administration (NARA), the Church of Jesus Christ of Latter-day Saints’ Family History Library and large public libraries. Still can’t find your ancestors arriving in America? Try checking the records of popular ports of departure.

If your kin applied for US citizenship, their naturalization papers will provide details about their immigration. Locating those documents can be a challenge, though: Until 1906, when the federal government standardized the citizenship process, immigrants could file for naturalization in any common law court in any state. Married women were tacked onto their husbands’ applications until 1922 and single women could submit applications, but rarely did.

We’ve wrangled up a list of websites, books and organizations to help you track down your on-the-move ancestors’ records. You’ll find everything from passenger lists to ship photos.

  • Check the date range of records in the database or index you’re using to ensure you’re searching records from the right time period. Such compilations of passenger-arrival information may not cover all ships or years — for example, Ellis Island’s Web site doesn’t include records for 1925 to 1954.
  • Despite popular lore, it’s a myth that officials at Ellis Island changed immigrants’ names. Passenger lists were filled out at the port of departure, and American clerks (fluent in many languages) only verified the names already on the lists. Those employees had strict instructions not to alter any information from the lists unless the inspection process revealed an error.
