Research Tip

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.
