In pirates of the Caribbean the pirate need the blood from what family?

In "Pirates of the Caribbean: The Curse of the Black Pearl," the pirates need the blood from the Turner family, specifically that of Elizabeth Swann, who is a descendant of the pirate Captain William Turner. This is crucial because the cursed treasure of the Aztec gold can only be lifted when the blood of all who were part of the curse is returned to the gold. Elizabeth's blood is required to complete the ritual and break the curse on the cursed crew.
