 John McCain's grandparents were natives of Arkansas, Mississippi, and Texas, and much of his ancestry was Southern on both his mother's side and father's side.The McCain family's patrilineal ancestral home is in Mississippi's Carroll County; they owned and ran a plantation in Teoc from 1848 until 1952.The plantation had slaves before the American Civil War – some of whose descendants share the surname and call themselves the "black McCains" – and sharecroppers afterward; influential blues guitarist Mississippi John Hurt was born on the plantation to one of the latter.
