Greene–Jones War
The Greene–Jones War was an ongoing Appalachian Mountain clan feud in the United States reputed to be second only to that of the Hatfield–McCoy feud in scale, duration, and number of persons killed. At least sixteen people, including one child, were killed during the course of the feud, and many others were seriously injured. The feud took place primarily in the border areas of Hawkins County (formerly part of Sullivan County, North Carolina, one of the earliest Tennessee counties and said to have a large Melungeon population), Washington County, Claiborne County, Hancock County, Tennessee (created when Hawkins County, Tennessee was subdivided), and Lee County, Virginia, not far from Cumberland Gap, the narrow Appalachian Mountain pass sometimes called The Wilderness Road leading into Kentucky.
Sutton–Taylor feud
The Sutton–Taylor feud began as a county law enforcement issue between relatives of Texas state law agent, Creed Taylor, and a local law enforcement officer, William Sutton, in DeWitt County, Texas. The feud cost at least 35 lives and eventually included the outlaw John Wesley Hardin as one of its participants. It started in March 1868, not reaching its conclusion until the Texas Rangers put a stop to the fighting in December 1876.
