I believe that you and I may be second cousins. My grandfather, Joseph Peloquin, born of Edward Felix (Peloquin) was likely your grandfather's brother. My father told me that "Auntie May" (Mrs. Dayan) would visit the house in Chippewa Falls and that my grandfather and her would speak "Indian" (presumably Chippewa since my father could understand and speak some French) with each other when they would visit.
Interestingly there is an Edward Felix (whom I believe could really be Edward (Felix) Peloquin) listed as a recipient of 80 acres as head of a "half-breed" household in the 1854 treaty with the Lake Superior Chippewa. Mary Dayan (nee peloquin) was born in Flambeau Wisconsin according to a book of births and deaths my father gave to me which was written in my grandmother's hand. Flambeau Wisconsin was a large Chippewa settlement at the time Mary (nee Peloquin or Felix) Doyen (Dayan?) was born and this corroborates part of the story. Supposedly Edward put her aside because she had been previously married and she didn't tell him. However, the custom of voyageurs at the time was to come and go (since many just died "en voyage" without a trace) so abandonment (intentional or not) of a spouse was common. Curiously, I am unaware of ANY corroborative evidence that Sophie Gauthier killed her self or her three sons. Such a tragic event would most definately been recorded or noted even in that time period. Wisconsin was wild then, but something like that would have been BIG news.
I find it interesting that there weresupposedly three sons that died at Sophie's hand, whereas Edward Felix (peloquin) had three sons, Edward (Felix) Paul (Felix), andJoseph (peloquin)- who was my grandfather.
