I wonder how many people were aware of the details of this feud prior to the History Channel's presentation last week. I also wonder how many Hatfields and/or McCoys around the country have been asked about their connection to it. The truth of the matter is that a McCoy in California has about as much connection to the feud as someone living in Russia. A "Real McCoy" is someone who grew up along the Tug Fork of the Big Sandy River, water that separated Kentucky and West Virginia. It just so happens that I did grow up in this area and heard about the feud all my life. The link at the bottom shows the territory where the fighting occurred.
Pretty impressive that this series set a cable viewership record each night during its showing.
