In the "Liber Defunctorum" (death registry) for St. Joseph Mission (La Pointe) and Holy Family Catholic Church (Bayfield)[edited and compiled by Linda Bristol, Bayfield, WI, 1994] there is this entry:
Nov. 30, 1880
Hilarii Genereux, age ca 65 years
Died: Nov. 27, 1880.
Cemetery: La Pointe.
Priest: Eustace Vollmer
Priest's notation: "Drowned in the Lake"
The cemetery "La Pointe" probably means the cemetery adjacent to St. Joseph's although it is possible it could mean the "Old Catholic Cemetery" at the original mission site south of the marina.
