For Some People of Appalachia, Complicated Roots

For centuries the Melungeon people of Appalachia believed they were of Portuguese descent. Turns out, their direct lineage is more African than anything else. Guest host Maria Hinojosa speaks with Roberta Estes, lead researcher on a recent study about the ancestral make up of the Melungeons. Also joining the conversation is Wayne Winkler, a Melungoen man and author of the book "Walking Toward the Sunset: The Melungeons of Appalachia."
