Au secours! Help with French, please.

I stand corrected! Forgetting what I know and don't know.

I have a death record on Ancestry 30 April 1906 for Emily Naylor (née Boudreault) with father Elwin Boodreau (one of the many spelling variations of Éloi Boudreault) and mother's name Mary Ann Lapernault. The entry is neatly typed on a card.

Vermont, U.S., Vital Records, 1720-1908 for Emily Naylor

From the PRDH website of Quebec genealogy (Programme de recherche en démographie historique):

Less than five months after the 8 January 1833 marriage above, on 22 May 1833, I find the birth of a daughter Marie Marguerite Boudreault (bap. 23 May) with father Éloi Boudreault and mother Marguerite Surprenant. I take this to be the missing surname of the bride Marguerite in the January marriage above.

And then on 29 November 1838 I find the birth of Emilie Boudreault with father Éloi Boudreault and mother Mary XXXXX and a footnote indicating that the recorder failed to indicate the surname of the mother. (Is this the same Emily that you mentioned finding, Kite, on my Henry Naylor thread? I should have asked where you found that.)

Trees on Ancestry differ as to whether Emilie's mother is Mary Ann Lapernault or Marguerite Surprenant. I looked everywhere for a Lapernault family and have found nothing credible. The trees with a lot of Québecois roots favor Surprenant. I think perhaps Lapernault is an English-speaking clerk's misreading of Supernault, which in turn seems to be a garbled version of the original surname Surprenant that came over from France.

Here's an example from FamSearch where the mother's name Delima Supernault on a death cert is transcribed as Delma Lupernault when it should say Supernault. The S is misread as an L. Moreover, the record has been attached by a user to Delima Surprenant.
Delma Lupernault aka Delima Surprenant

The Canadian censuses in that time and place show an array of Supernault, Supernant, Supernand, Suprenan, Surprenant, Supernan, Surprenaut variations in the same families.

Emily's death cert is wrong on other counts as well, including her birthplace.

I have not found any reason to believe that Éloi Boudreault remarried between 1833 and 1838.

I want to conclude that Mary Ann Lapernault and Marguerite Surprenant are one and the same.

Sorry for the length... Now please tell me whether I am raving.

I don't remember where I found an Emilie Boudreau three years ago, sorry! But there is this public tree on Ancestry:

And I can well imagine that Lapernault is a mistranscriptiohn of Suprenault / Surprenant.

Thank you! Much appreciated, Kite. I thought I might be losing my mind.

EDIT:
That tree looks quite helpful. Thanks for that.
