Thank you for trying to help.I know that there are several different history regarding the first Duplessis of my family.I wish someone could show me the proof that Jean-Baptiste is the son or adopted son of Louis Gatineau.If he was adopted son of Louis Gatineau, in my mind, my tree stops at Jean-Baptiste.
Some say that Jean-Baptiste was Louis Gatineau's slave.I believe it could be possible.I found the baptism of a 'little indian" that belongs to Louis Gatineau.He was named Jean-Baptiste, no family name.In a slave book, I saw him as Louis Gatineau's slave and as my ancestor.That would make sense.
I have right now in front of my eyes a copy of the parish record when Marie-Anne was baptized. and it says "... has been baptized Marie-Anne born the same day, daughter of Baptiste called Duplessis and Françoise Lacerte."
They don't says Baptiste Duplessis, they say Baptiste dit Duplessis.I think if he was the son of Louis Gatineau or adopted son of Louis Gatineau they would not write it.Louis Gatineau was somebody important.
I also have in front of my eyes the burial of Jean-Baptiste:
On September 16, 1816 by us, priest of Pointe du Lac undersigned, has been burried in the cemetery of this parish the body of Jean-Baptiste Duplessis, 64 years old....."The only Duplessis that was 64 years old or about 64 years old is the Joseph born February 20, 1753.This is one of the clues that make be believe that the Jean-Baptiste who married Josephte Turcot was the Joseph born in 1753.
I am glad that you brought this up, may be somebody will help us.
