The two families have been working together for quite a while. My father used to work for a real estate and development company that sold some land in West Virginia and Kentucky to some McCoys. The construction company that built the shopping center on each piece of property was owned by some Hatfields. He said the two groups got along just fine and joked about the whole feud thing.
That's what I figured. The History Channel's just trying to find a way to mix "Moonshiners" and other popular series together.
