Larrys Creek is named for Larry Burt, the first European settler in the area, who lived near the mouth of the creek outside what is now the hamlet of Larrys Creek in Piatt Township. He traded with the indigenous peoples, and, according to a tradition reported by Meginness (1892), he had a Native American wife. Larry Burt was already there when surveyors came through in 1769 (after the land was purchased by the colonial government of Pennsylvania on November 5, 1768 as part of the "New Purchase" in the first Treaty of Fort Stanwix), but disappeared sometime soon after, perhaps moving west with the Native Americans who left the area.
