Appalachian folk tales are rooted in English, Scottish, and Irish fairy tales, as well as regional heroic figures and events. Jack tales, which tend to revolve around the exploits of a simple-but-dedicated figure named "Jack", are popular at story-telling festivals. Other stories involve wild animals, such as hunting tales. In the industrial areas of western Pennsylvania and northern West Virginia the composite Joe Magarac steelworker story has been handed down. Regional folk heroes such as the railroad worker John Henry and frontiersmen Davy Crockett, Mike Fink and Johnny Appleseed are examples of real-life figures that evolved into popular folk tale subjects. Murder stories, such as Omie Wise and John Hardy, are popular subjects for Appalachian ballads. Ghost stories, or "haint tales" in regional English, are a common feature of southern oral and literary tradition. Ghost stories native to the region include the story of the Greenbrier Ghost, which is rooted in a Greenbrier County, West Virginia, murder.
