A recent online article from the Westchester Journal News discusses the location of African American cemeteries in New York State.
The list includes prominent ones like the African Burial Ground National Monument in Lower Manhattan. Some are hidden within larger cemeteries like Green-Wood Cemetery in Brooklyn. There are those forgotten for years until supporters stepped forward to preserve them like the Pine Street African Burial Ground in Kingston. Some are even buried literally by development like the African Methodist Episcopal Church Cemetery in Staten Island.
