On Friday's episode, BackStory digs into the complicated history of 1619 and the 400th anniversary of the arrival of the first Africans to the English colonies.  In this preview, BackStory travels to Hampton, Virginia to meet with members of the Tucker family. Using oral history and official records, they’ve traced their lineage back to William Tucker, the first African American born in British North America in 1624.  Image: BackStory producer Melissa Gismondi speaks to Walter Jones, Vincent Tucker and Verrandall Tucker, at the Tucker family cemetery in Hampton, VA.
