Research Tip

Immigration records pertain to people moving from one country to another and can include ship passenger lists, naturalization documents, immigration/emigration information, etc. Passenger lists often give names and ages of individuals and sometimes their place of origin. If people traveled with family members, they were usually listed together on the passenger lists. Naturalization documents can list a person's name, age, witnesses, and place of origin. In some cases, women were not required to naturalize separately from their husbands. Before 1906 in the United States, naturalization documents sometimes only listed a home country rather than a specific town or city where a person came from. Since 1906, more detailed information has been included in naturalization documents.
