I don’t know if this is the family that you are looking for but it sounds like it could be. The Louis Pichon that you may be referring to is in the 3rd generation.
Louis Pichon was born 26-Oct-1842 and died 22-Mar-1907. Zelia Meulin was born 23-Mar-1842 and died 26-Oct-1926. Louis and Zelia had 10 children.Gustave was the oldest.
Gustave Pichon was born in 1866 and died in 1947. Eva Orlia was born in 1866 and died in 1945. Gustave and Eva had 5 children.Louis was the oldest.
Louis Pichon was born in 1889 and died in 1979. Elsie – dates unknown Louis and Elsie had 2 children.They were William and Sandra. Louis had 3 brothers (Edward, Paul, & Walter) and 1 sister (Rose) As far as I know, they born and raised in or around Batestown, IL. Batestown is just West of Danville IL which is on the Indiana boarder. Most of these folks are buried in Oak Hill Cemetery in Batestown although I do not believe that the younger Louis is there. Edward was my great-grandfather.
I have some additional information about the family if you are interested but I think that this is all I have specifically about Louis.
