In the Season 2 finale, DNA analysis uncovers previously unknown roots in the family trees of Jessica Alba and Massachusetts governor Deval Patrick. Alba, for instance, learns that she's descended from the official cartographer of France's King Louis... (more) XIV; and Patrick discovers his ancestors include a black homesteader in Colorado. DNA analysis is also used to delve deeper into the family histories of Anderson Cooper, Valerie Jarrett and host Henry Louis Gates Jr. himself.
