The Fox sisters were three sisters from New York who played an important role in the creation of Spiritualism: Leah (1831-1890), Margaret (also called Maggie) (1833–1893) and Kate (also called Catherine) Fox (1837–1892). The two younger sisters used "rappings" to convince their much older sister and others that they were communicating with spirits. Their older sister then took charge of them and managed their careers for some time. They all enjoyed success as mediums for many years.
In 1888, Margaret and Kate confessed that their rappings had been a hoax and publicly demonstrated their method. Margaret attempted to recant her confession the next year, but their reputation was ruined and in less than five years they were all dead, with Margaret and Kate dying in abject poverty. Spiritualism continued as if the confessions of the Fox sisters had never happened.
In 1848, the two younger sisters – Kate (age 12) and Margaret (age 15) – were living in a house in Hydesville, New York with their parents. Hydesville no longer exists but was a hamlet that was part of the township of Arcadia in Wayne County, New York just outside Newark. The house had some reputation for being haunted, but it wasn't until late March that the family began to be frightened by unexplained sounds that at times sounded like knocking and at other times like the moving of furniture.
In 1888, Margaret told her story of the origins of the mysterious "rappings":
During the night of March 31, Kate challenged the invisible noisemaker, presumed to be a "spirit", to repeat the snaps of her fingers. "It" did. "It" was asked to rap out the ages of the girls. "It" did. The neighbours were called in. Over the course of the next few days a code was developed where raps could signify yes or no in response to a question or be used to indicate a letter of the alphabet.
The girls addressed the spirit as "Mr. Splitfoot" which is a nickname for the Devil. Later, the alleged "entity" creating the sounds claimed to be the spirit of a peddler named Charles B. Rosna, who had been murdered five years earlier and buried in the cellar. In his writings on the Fox sisters, Arthur Conan Doyle claimed the neighbors dug up the cellar and found a few pieces of bone, but it wasn't until 1904 that a skeleton was found, buried in the cellar wall. No missing person named Charles B. Rosna was ever identified.
