Hatfields and McCoys -- a new look at an old fued

We've all heard of the infamous fued between Hatfields and the McCoys. What we probably didn't know is that is the fued may have some genetic underpinnings. In her article, "Genetic Health Found in Famous Feud Family," Melissa Slate, who writes on the genealogy research in the Appalachian region, discusses a rare genetic disease affecting those on at least one side of the fence, the McCoy family. Among the symptoms . . . increased rage. But as Melissa points out, this is more than a historical anecdote; being genetic the disease can be passed down, and researchers are keenly interested in locating descendants of McCoy family.
