Bathsheba was born in the 1800s and was claimed to have been related to Mary Towne Eastey, one of the many executed for witchcraft in the Salem witch trials of 1692.
In 1863, Bathsheba married a rich farmer under the surname "Sherman" and gave birth to a child. When it was a week old, her husband caught her sacrificing her baby to the Devil, to which she climbed a tree outside and hung herself before proclaiming her love to Satan and cursing anyone who tried to take her land. Her spirit lived on, possessing women living at her farmhouse and using them to sacrifice their children to the devil. Ed and Lorraine Warren try to stop her, and in retaliation their daughter Judy is attacked in their own home by Bathsheba with help from a demonic-possessed doll, Annabelle, from one of Ed and Lorraine's previous cases. However Ed arrives in time to stop her from harming their child. Bathsheba goes on to possess Carolyn, the motheir of five daughters and wife of Roger Perron. Ed, Lorraine and Roger rush to the house where they find the possessed Carolyn trying to stab one of her daughters with scissors. After subduing Carolyn, Ed decides to perform a exorcism though Carolyn escapes and again attempts to kill her daughter Lorraine is able to temporarily distract the possessed Carolyn by reminding her of a special memory she shared with her family, allowing Ed to complete the exorcism, saving Carolyn and her family and banishing Bathsheba.
