For this holiday episode, we're bringing you a story from the Radio Diaries podcast, The Unmarked Graveyard: Stories from Hart Island. Hart Island is a narrow strip of land in New York, off the coast of the Bronx. More than a million people are buried there in mass graves, with no headstones or plaques. Annette Vega never met her biological father. She had been searching for him for decades. That search finally led to Hart Island. Along the way, she found the family that she never knew.
