The movie was pretty accurate historically. My g-grandfather was in the same CSA unit with Captain Devil Anse, 45th Virginia and later the "Logan Wildcats". He lived very close to him in Logan County, WVA and he when the feud broke out he sided with the Hatfields. They fought for Virginia because West Virginia was still Virginia when the war broke out. My g-grandfather was also in the same unit and he joined the CSA at age 56. This area of (West) Virginia was pro-Confederate and the people identified as Virginians.
This is my g=grandfather with his wife and youngest child. He had about 10 young-uns.
The rifle is a Sharps carbine he used in the war. My grandfather had a rifle that had "Devil Anse Hatfield" engraved in the stock and my cousin was with him one day when he traded it for a pony. My cousin told him to hold onto it because it was valuable and grandpa answered who would want a that. They are getting ready to head to church. A rifle in hand. LOL
