Historical vampires: Smithsonian has a good article on New England vampire scares in the 19th century.
It's a mix of sad tales about families and illness, along with practical responses.
Some communities in Maine and Plymouth, Massachusetts, opted to simply flip the exhumed vampire facedown in the grave and leave it at that. In Connecticut, Rhode Island and Vermont, though, they frequently burned the dead person’s heart, sometimes inhaling the smoke as a cure.
