Priscilla’s Story: Family traces roots to slave island

NBC News Correspondent Ron Allen journeys to Bunce Island off the coast of Sierra Leone.  Bunce Island was once a slave trading fortress, which served as the beginning of a tragic journey for tens of thousands of Africans transported across the Atlantic into slavery in the United States. One African-American family, the Martins, was able to trace its roots two and a half centuries back to the island and to a little girl named Priscilla who was sold into slavery when she was 10 years old. Feb. 16, 2012
