By the mid-17th century, the French had begun to send expeditions into Wisconsin via the Great Lakes and Saint Lawrence River. King Louis XIII of France is believed to have granted a huge area of land in the Upper Mississippi River Valley to two brothers, Etiene Pepin de la Fond and Guillaume dit Tranchemontagne. Two of Guillaume’s sons, Pierre Pepin and Jean Pepin du Cardonnets, later explored and traded in this area, and their surname became attached to the lake, and ultimately to the village and the county.
