It is very likely that we may be related. I have 2 Louis Charbonneaus in my family and one did return to Canada. What year was Louis/Lewis Charbonneau born? Was his father Joseph Charbonneau? My Louis Charbonneau was my great granduncle and was born about 1834.
I have the Charbonneau/Sharbono family tree back to about 1590 if you are interested.
