Daniel Stoy was one of the first settlers west of the mountains. From the records of Harmon Husband, we find that Stoy lived along the Forbes Road about 1762 near the Casper Stotler place in Shade Township, that he made his living by hunting, and that he was driven from his cabin home several times by the Indians, taking refuge at Fort Bedford. The records of Husband state that on one occasion Stoy shot an Indian intruder from his cabin door. With the construction of the Pennsylvania Road, Stoy decided to move to a place about ten miles farther west along the road where he received a warrant for more than three hundred acres of land. Here on this tract of land along the Pennsylvania Road, he founded the town of Stoystown in 1774. Stoy served as a volunteer in the Revolutionary War with the rank of corporal.
