Mercy Brown
Rhode Island
Named after the deceased 19th-century Rhode Island resident, young Mercy Lena Brown.
Despite being dead and buried during the coldest winter, her exhumed corpse was found to be biologically immaculate and perfectly preserved, indicating supernatural vampirism to the superstitious locals.
Interred in the frozen graveyard of the Baptist Church in Exeter, Rhode Island.
Operating as an undead parasite, she was believed to systematically target and drain the life from her surviving living relatives.
When George Brown's relatives kept dying without medical explanation in 1892, panicked locals dug up the graves to investigate. Diagnosing her as a vampire, they burned her heart and liver to create a tonic for her sick brother, who tragically died two months later.
