As a descendant of the Hatfield clan I found everything shown in this mini series mostly true. As a young teenager I did a report on it for school. The Johnse/Rosanna romance was true. As for Johnse being a romancer of women Rosanna even mentions that in part 1. The stolen pig is true along with the all of the killings that took place. The only parts I haven't confirmed in my time on earth is the part where Devil Anse takes Johnse fishing to find out if he told Nancy where the Hatfields were and Devil Anse being baptized. It's by far the best movie production by far about the feud. A lot of the little things like the 2 guys cutting the tree on the down hillside which isn't the way to cut a tree doesn't bother me. The major points of the feud were brought out n now a lot more know about history of the Hatfield & McCoys.
