When Katrina Browne was 28 years old and in seminary, she learned that her ancestors were the largest slave-trading family in U.S. history. And, they were not from the South; they had lived in Rhode Island. Katrina wrote to 200 family members, inviting them to explore their family's past. The result: an award-winning documentary, Traces of the Trade, made with co-producer Juanita Brown, who helped plan a journey to Africa for the group and facilitate painful conversations about their discoveries.
