Melungeon (/məˈlʌndʒən/ mə-LUN-jən) is a term traditionally applied to one of numerous "tri-racial isolate" groups of the Southeastern United States. Historically, Melungeons were associated with the Cumberland Gap area of central Appalachia, which includes portions of East Tennessee, Southwest Virginia, and eastern Kentucky. Tri-racial describes populations thought to be of mixed European, African and Native American ancestry. Although there is no consensus on how many such groups exist, estimates range as high as 200. Melungeons were often referred to by other settlers as of Portuguese or Native American origin.
According to the Tennessee Encyclopedia of History and Culture, in his 1950 dissertation, cultural geographer Edward Price proposed that Melungeons were families descended from free people of color (who were likely of both European and African ancestry) and mixed-race unions between persons of African ancestry and Native Americans in colonial Virginia.
The ancestry and identity of Melungeons has been a highly controversial subject. Secondary sources disagree as to their ethnic, linguistic, cultural, and geographic origins and identity, as they are of mixed racial ancestry. They might accurately be described as a loose collection of families of diverse origins who migrated, settled near each other, and intermarried, mostly in Hancock and Hawkins counties in Tennessee, nearby areas of Kentucky, and in Lee County, Virginia. Their ancestors can usually be traced back to colonial Virginia and the Carolinas. They were largely endogamous, marrying primarily within their community until about 1900.
