Grave of Ed and Lorraine Warren

In life, husband-and-wife duo Ed and Lorraine Warren were some of the most prolific paranormal investigators in American history. Their real escapades inspired one of the highest grossing fictional horror franchises, The Conjuring Universe. The pair of devout Catholics also ran the Occult Museum for many years.

Ed claimed to be a demonologist, while his wife Lorraine was a self-professed clairvoyant. Together, they traveled the country, investigating infamous cases such as the Enfield poltergeist, an alleged instance of possession that formed the basis for The Conjuring 2, and Amityville Horror, a prominent 1975 case in which a couple claimed that a demonic presence haunted their home, as well as the 1968 case of a haunted Raggedy Ann that inspired the cinematic murder doll, Annabelle.
