>>I have accessed Edward's birth and bapt. record today and read that he was born July 20th 1851 and bapt.13 Jun 1852. This record was recorded by a missionary deserving the area. At the beginning of the record, St-Alphonse has been deleted. This leads me to believe that the baptism took place during a trip of the regional missionary. Mary Ann's surname appears to read as : Pogarthy vs Forgarthy.<<
I disagree with your assertion.
While these bap records are primary, they're not without error. I built out the generation of children, and this bap record is for (2nd child born) Richard, born 20 FEB 1852 and baped 13 Jun 1852. The priest was not consistent with formatting. The scratching out of St Alphonse is open for speculation, could have been due to distraction. I see the mother's name Fogarty. You see a "P", I see an "F". You see July, I see Feb. I'm confident in my evaluation of the data. Richard died in 1886 and never married.
The bap record for Edward (1st known born) is found in the same parish, and it has some irregularities as well. The surname is Gaunon and father is cited at "Edward", the mother is Marie Anne Fogarty. Eward was born 1 Dec 1850 and baped 21 Jan 1851. As I mentioned previously, the godparents are the same couple Marie Anne Fogarty and her son Edward Gagnon are living with in the 1851 Census.
Edward Gagnon's birth date is cited as (?) Dec 1850 in the 1901 Census. The "day" is a single digit, the transcriber guessed it is a 6, but it doesn't really matter, it's a single digit.
That's 3 pieces of evidence which qualify my assertion. All the docs are linked to the entries in my public member research tree. The Drouin copy of this parish is misty, I suggest using the familysearch.org copy.
I stand by this assertion made previously: "There is the possibility they were not married in the Catholic Church as Mary Ann Fogarty is cited as "Protestant" in the 1851 census, as is her son Edward (b 1850), however Edward was baptized in the Catholic Church (19 Jan 1851), the bap document verifies this.
