“Like most frontier outposts, the Conococheague Settlement was an occasional target for Indian raids. On one such occasion, a raiding party of Susquehannas captured a young Scotchman named Peter Williamson, and forced him to carry their loot. He later escaped, or was freed, and lived to a ripe old age,” Frank Mentzer, superintendent of Catoctin Mountain Park, wrote in the September 7, 1968, Catoctin Enterprise.
Mentzer made the case that the Jacob Snider family was massacred by Indians in the late 1700′s. He based his belief on an account written by Williamson called The Life and Curious Adventures of Peter Williamson, who was Carried Off from Aberdeen, and Sold for a Slave.
