Tracing an ancestor who was an immigrant

African-Americans

The overwhelming majority of Americans of African ancestry are descendants of slaves forcibly brought to the New World during the 18th and 19th centuries. Most of these slaves were members of societies living within 300 miles of the Atlantic coast between the Congo and Gambia rivers in west Africa. In addition, since the end of World War II, a significant number of people of African ancestry have emigrated to the US from the Caribbean (see West Indians), where their ancestors were also slaves (primarily at the hands of the British, Dutch and French).
