A great source of tracing early African and African American ancestors is the Virginia Gazette. Slave owners ran ads describing in great detail their runaway slaves, apprentices and indentured servants. Many of these ads list native Africans, their ethnicities, country of origins, their owners, how long they had been in the colonies, and the ships they came on. These records are online at http://etext.virginia.edu/subjects/runaways/1740s.html.
