This is the name of a creek, part of which flows through Sullivan County. The name "Loyalsock" is a corruption of the Indian word "Lawisoquick", meaning "middle creek". It was within historic times that at the mouth of this creek the Ostonwakin Villae was situated. On old maps the village was marked as being on the western side of the creek at the mouth.
