On September 28th, we’re launching a new series: The Unmarked Graveyard: Stories from Hart Island. Hart Island is America’s largest public cemetery—sometimes known as a “potter’s field.” The island has no headstones or plaques, just numbered markers. More than a million people are buried on Hart Island and many are shrouded in anonymity. Explanations for how they ended up there can be hard to find. Over the next seven weeks, we’ll untangle mysteries about the lives they lived and the people they left behind.
