Jean Baptiste Tremblay and Geneviève Marney I find having some of their children baptized as follows (in Drouin collection online):
Jean Baptiste Tremblé, b 18 nov 1802 bapt 9 Jan 1803 St-Luc (St-Jean), mother listed as Geneviève Richelieu dite Bernier (Only one like this)
Antoine Tremblé, b 26 Jul 1804 bapt 3 Mar 1805 St-Luc (St-Jean)
Édouard Tremblay, b 13 Jun 1810 bapt 31 Jan 1811 La Prairie
Émilie Tramblay, b ? bapt 12 Jan 1817 L'Acadie
Laurent Tramblay, b 6 Sept 1820 bapt 6 Jan 1821 L'Acadie
There is a Bruno Tremblay (their son) who marries Appoline Lamoureux on 12 Oct 1830 in L'Acadie, residence for him and his parents is Chazy NY.
On the first 3 baptisms found they are listed as residents of Lake Champlain, Jean Baptiste being farmer there. On the last 2 they're listed as living in Chazy NY. No marriage found for them here. Indications from the baptisms makes me think the godparents' residences were the factor in where the kids got baptized.
So, quite possible that you have the right parents for him. The DOB you have for him fits in among others. Took a look to see if I could find a baptism for him this side of the border, no luck, he has THE most common family and given names around here.
