William Wilson (ca. 1762 – October 1821) became a figure in the folklore of southeastern and south-central Pennsylvania in the late 18th century and early 19th century. He is often referred to as The Pennsylvania Hermit. His sister Elizabeth had been condemned for the murder of her children, although many believed her to be innocent of those charges. A pardon for Elizabeth was granted by the state and entrusted to William, but he was unable to deliver it in time to stop the execution.
