Looking for marriage record of Gedeon Frappier and Mathilda Derouin. He was born 1861, PQ died 15 Jan 1892 at Springer  Twnshp, Ontario. Had child born in Rockland, Russell 19 Jul 1889 and another 28 Apr 1887 at Buckingham.

I can't find Gedeon Frappier's marriage act.  But here's what I found.  Gédéon was Mathilde's second husband.  On her first marriage, she married William Foubert :  https://familysearch.org/ark:/61903/3:1:3QSQ-G993-6S1Y?i=168&wc=9RL6-DPV%3A13626501%2C13626502%2C13628103&cc=1321742

Can't find William's death act.  With Gédéon, Mathilde had these children :

Gédéon Flavien, born february 1st 1884, baptized in Angers on february 10th.  Godmother was Angélique Derouin.

David Napoléon, born august 3rd 1885, baptized in Angers on august 9th.  Godfather Flavien Derouin, uncle of the child.

Joseph Modeste, born april 29th 187, baptized in Angers on may 1st.  Godmother Olive Derouin, aunt of the child.

Joseph Télesphore was the one born in Rockland, Ontario.

Gédéon was son of Prospère and Adèle Grignon.  On the 1871 Census, we can see that he's 13 and he has a sister named Eugénie.  Here's Gédéon's baptism act  ( B53 ) :  https://familysearch.org/ark:/61903/3:1:3QS7-L993-XS36?i=335&wc=9RL6-FM4%3A18615001%2C18615002%2C19036501&cc=1321742 .  We read Napoléon but Gédéon also appears in the index :  https://familysearch.org/ark:/61903/3:1:3QS7-8993-X9RM?i=359&wc=9RL6-FM4%3A18615001%2C18615002%2C19036501&cc=1321742.

His sister Eugénie married Delphis Derouin, Mathilde's brother, on June 9th 1883 at Buckingham.

Thanks Yves, this is the family. Fabin's birth record matches census from Springer, Ont and his grave marker in Mich.

the baptismal act for gedeon or Napoleon that you refer to (53) is a son of Louis Frappier and Anastasie Cayer

You're right.  Gédéon's act number and folio are missing in the index.  Here's the good one : https://familysearch.org/ark:/61903/3:1:3QSQ-G993-XS96?i=312&wc=9RL6-FM4%3A18615001%2C18615002%2C19036501&cc=1321742

Yves.

Thanks again Yves. This sure looks like my guy.

Do you have Mélanie Serre's  parents marriage ?

Yves.

No I don't. Would they be Gabriel Serre and Rachel? They were neighbors of the Frappiers at Springer, and after Gedeon died, Mathilda married Joseph Serre, probably a brother of Gabriel's. 

Gabriel Céré and Rachel Jodoin marriage ( M-12 ) : https://familysearch.org/ark:/61903/3:1:3QSQ-G993-XHXY?i=448&wc=9RL6-RM3%3A13628301%2C13628302%2C13628303&cc=1321742
