The story of the Melungeons is at once a footnote to the history of race in America and a timely parable of it. They bear witness to the horrors and legacy of segregation, but also to the overlooked complexity of the early colonial era. They suggest a once-and-future alternative to the country’s brutally rigid model of race relations, one that, for all the improvements, persists in the often siloed lives of black and white Americans today. Half-real and half-mythical, for generations the Melungeons were avatars for their neighbours’ neuroses; latterly they have morphed into receptacles for their ideals, becoming, in effect, ambassadors for integration where once they were targets of prejudice.
