Hathorne, showing a momentary doubt about her guilt, went so far as to ask the girls if they were quite sure that Mary Eastey was the woman who afflicted them.
Robert Calef, in More Wonders of the Invisible World, described Eastey's parting words to her family "as serious, religious, distinct, and affectionate as could be expressed, drawing tears from the eyes of almost all present".
Of her two sisters, likewise charged with witchcraft, Rebecca Nurse was hanged on July 19, 1692, but Sarah Cloyce was released in January 1693.
Herrick testified that she was visited by Eastey's ghost, who told her she had been put to death wrongfully and was innocent of witchcraft, and that she had come to vindicate her cause.
