If your ancestors immigrated, a paper trail documented almost every step of their journey — from the ship they boarded to the day they became citizens. Here is how to find it.
For researchers with immigrant ancestors — and that covers the majority of people tracing North American, Australian, or South American family lines — immigration records are often the most revealing documents in the entire genealogical archive. A passenger list from 1902 might confirm not just when your great-grandparent arrived but the exact village they came from, who they were travelling to meet, and how much money they had in their pocket. This guide walks through each type of record and where to find it.
Passenger lists were created by shipping companies and submitted to port authorities on arrival. Their content changed significantly over time. Lists before about 1895 typically record only the passenger's name, age, nationality, and destination. Lists created after 1895 — and especially after 1906, when the US required expanded information — record the town of last residence or birth, the name and address of the contact in the destination country, and the passenger's physical description.
The post-1906 passenger lists are the most genealogically valuable documents in American immigration history. The "last residence" column on many manifests gives you a specific village rather than a country — pinpointing exactly where to search next.
Naturalization was a two-step process for most of American history. The first step was filing a Declaration of Intention (informally called "first papers"), in which the immigrant declared their intention to become a citizen and renounced allegiance to their country of origin. The second step was the Petition for Naturalization, filed after a waiting period, which granted citizenship on approval.
Post-1906 declarations of intention are particularly valuable. They record the immigrant's exact birthplace, physical description, occupation, and the names of witnesses. If you have an immigrant ancestor who naturalized after 1906, their declaration of intention is likely the most specific record of their origin you will ever find.
The US-Canada and US-Mexico borders generated crossing records for overland immigrants. Canadian border manifests, maintained from 1895 onwards, recorded the same detailed information as ship manifests. Many Canadians who later moved to the US crossed at land borders and appear in these records.
The major genealogy platforms have digitised and indexed most of the surviving US immigration records, making them searchable by name:
Early 19th-century passenger lists are straightforward — just a few columns of information written in clear copperplate handwriting. Later manifests, particularly the post-1906 forms, are more complex. The standard form has 29 columns and was handwritten by a ship's purser, often in a hurry, in a mix of languages.
Common challenges when reading old manifests:
Tip: If you cannot find an ancestor in a passenger list, try searching by the name of the contact listed in the destination country. If your ancestor was travelling to meet a brother, the brother's name appears in the manifest — and the brother may be easier to find in US records first.
Finding the specific village your ancestor emigrated from is one of the most exciting moments in genealogical research — and the gateway to a completely new set of records. Church records (baptisms, marriages, burials) in European, Latin American, and other countries were often kept at the parish level and have survived in remarkable quantity. Many have been microfilmed by the LDS Church and are searchable on FamilySearch. Others are held in regional or national archives and may require a direct request or an in-country researcher.
Once you have a village, record it in your family tree tool alongside the individual. Build My Family's birthplace field accepts free-text entries, so you can record the full original village name and country. This information becomes the starting point for your next phase of research into pre-immigration records.
Build My Family lets you record birthplaces, immigration dates, and biographical notes for every family member. Export to GEDCOM for sharing with international genealogy platforms.
