One explanation for what is written on her headstone could be this: Before modern psychology/medicine, those who would now be considered insane or have mental illnesses, would back in the olden days before our modern 21st century, have been considered by the Christian community (especially the Catholic faith at the time) as demoniacally possessed. Could it be possible that Lilly E. Gray simply had a mental illness that was thought to be demonic possession by the overpowering and dominating religious community that most likely surrounded her? Take a look at the Salem Witch Trials. Do you REALLY believe all those young girls where witches? Or was the religious community at the time too narrow minded to see that they most likely were not witches, but bored girls who wanted to have something to do so they played a "game" or prank on their community with deadly results? So anyway, just thought I would try to give a new view that I have not seen anyone bring up yet about Lilly E. Gray.
