History & local legend
Indian Echo Caverns near Hummelstown sheltered William Wilson from 1802 to 1821. Known as the Pennsylvania Hermit, he withdrew from society after his sister Elizabeth was executed in Chester for the murder of her children.
The tradition says William obtained a pardon but arrived too late to prevent the hanging. His unsuccessful ride became a story in its own right, while the caverns beside Swatara Creek became associated with the years of isolation that followed.
Elizabeth’s supposed appearance happened above ground. Workers clearing trees for a parking lot reportedly saw a young woman wandering nearby. Later storytellers identified her as William’s sister, linking the figure outside the cave to the family tragedy behind the hermit’s retreat.
