I've written about my cousin Katrina Browne's documentary, Traces of the Trade, in the past. It's going to be shown tomorrow night (June 24) on the PBS program POV.
After Katrina discovered that our ancestors were slave traders, she set out to trace the journey made by the traders and slaves, with a group of family members. It promises to be a fascinating show. I've only seen the trailer so far. I had the same experience as my sisters, who commented that it was hard to watch all the way through because they kept saying, "Hey! There's Dad! Look, it's Aunt Lidy!"
Here's the trailer.
