Pepin County was formed in the year 1858 from portions of neighboringDunn County. Both thetown of Pepin (originally named North Pepin in 1856), and thevillage of Pepin were named afterLake Pepin, a broadening of theMississippi River between Pepin County and the Counties ofGoodhue andWabasha in the state ofMinnesota. The lake itself is likely named for one or more of the Pepin families from the French Canadian city ofTrois-Rivières inQuebec,Canada. Several Pepins appear in the early records, including the senior figure Guillaume dit Tranchemontagne and his descendants Pierre and Jean Pepin du Chardonnets. One or both of the latter may have accompaniedDaniel Greysolon, the Sieur du Lhut, fromMontreal to what is nowDuluth, Minnesota, in 1679. Exactly when the body of water was first named Pepin is not known, but the name has been used as early as 1700, making it by far one of the oldest recorded place names in Wisconsin. The name was well accepted by the mid-1760s whenJonathan Carver wrote in his journal, "Arrived at Lake Pepin called by some Lake St. Anthony."[5]
