I found something you probably missed because it's in french. You can reach one of your cousin Michel Duplin at
graphmic@videotron.ca .
I offer you a translation of the text I found in
http://www.autochtones.com/fr/cherche/index_p7.htmlIt goes like this :
------------------------------------------------------------
I'm looking for information to identifie the tribe and origin place of my ancestor Louis [Duplin...] who has been baptized in St-Pierre les Becquets in February 19th 1816. According to the baptism register, he was 12y 4m old and was then with a woman called Marie-Louise of 28yo, and two young girls. One of the young girl named Marie-Louise two was born on Nov 8th 1809, and the other young girl was born about Aug. 1st 1811. The preacher indicated that the young girls was coming from the Uplands. It's Louis Trottier dit Labissonnière, a "coureur des bois" for the Baie d'Hudson Cie who brought back all theses peoples with him from the Uplands. During this same day Feb. 19th 1816, he married the older Marie-Louise and recognized the young girls like its natural children. Louis [Duplin...] didn't had a family surname when he was baptized, but he use to be called Louis D'upland ( In french " D' " means "from" so it means Louis From upland ) When he married Marguerite Rancourt in Feb 22th 1830, the preacher wrote Louis Duplin.

I think you will have some difficulties to find ancestors older than Louis because he was amerindian. In most of case, we have difficulties to find information about amerindians because there was no or a few registers only holded by these peoples. I know that near St-Pierre les Becquets, there is an Abénakis tribe at Bécancour and also at Odanak.
Another hint, a lots of Louis and Marguerite daughters married some Grégoire and Godbout in Wotton, St-Camille-de-Wotton and St-Joseph de Ham-Sud. All of it are always located in Wolfe County, Québec, CA.

Oh, another hint !! Install french keyboard on your computer to be able to have the accents " é à ç î è ô ... " If you don't type names and surnames with their accents, your research will be erroneous and you will post name with errors. So I corrected the names of your ancestors and gave you the ""phonetic"" pronounciation where it is difficult.

It's all about what I found in one evening. I hope it may help you. If you have something to translate or if you need anything else, just send it to me by email. I have a good geographic knowledge about Québec and all your ancestors lived where my current family descendants lives...
Good luck Barbara
