In 2001, at forty-seven, Thomas DeWolf was astounded to discover that he was related to the most successful slave-trading family in American history, responsible for transporting at least 10,000 Africans to the Americas. His infamous ancestor, U.S. senator James DeWolf of Bristol, Rhode Island, curried favor with President Thomas Jefferson to continue in the trade after it was outlawed. When James DeWolf died in 1837, he was the second-richest man in America.When Katrina Browne, Thomas DeWolf's cousin, learned about their family's history, she resolved to confront it head-on, producing and directing a documentary feature film, Traces of the Trade: A Story from the Deep North. The film is an official selection of the 2008 Sundance Film Festival.
