What became of Anne-Helene Bardet born 1692?

For years the internet French-Canadian genealogy community has persisted in identifying our Anne-Marie Bardet, wife of Joseph Larchevesque of Canada as the child born 8 February 1692 and baptized at Saint-Barthelemy de La Rochelle daughter of Pierre Bardet and his wife Marie de Moucheron. Our ancestor was actually an older sister to this Anne-Helene. Our ancestor Anne-Marie was born 6 Jan 1688 and baptized at Saint-Barthelemy.

Tonight I have discovered the fate of the younger sister previously identified in all online sources as our Anne.

De 1686 à 1789, le couvent des Dames de la Foi, à Pons, a servi de lieu d’endoctrinement des protestantes pour les faire revenir à la religion catholique. On les appellait "les Nouvelles Catholiques". Quelques détails révèlent les méthodes employées.

"Bardet, Hélène, 19 à 20 ans, de La Rochelle, fille d’un commissaire de la marine, décédée, 30 septembre 1711-15 janvier 1712."

This fits very well with the baptism in 1692 incorrectly attributed to our Anne

Our Anne married under the first name Anne 

She died 29 August 1752 aged 63 years (born about 1689) 

This explains everything

it appears our Anne-Marie (aka Anne-Helene) had an illegitimate child ... born the 11th and Baptized the 12th of December 1707 in The parish of Saint-Barthelemy-de-La-Rochelle
She named her Marie, most likely for her mother Marie de Moucheron

Anne-Helene's Marriage and burial Records...

It is my intention to upload each and every document I can which relates to her life and ancestry.

Here is her 1719 Marriage to Joseph-Nicholas Larchevesque...

and her burial record :

Anne-Helene's baptismal record

I would like to start by correcting an error perpetuated on the internet that gives Anne's date of birth as 8 February 1692. Actually that is the baptism date for her younger sister Helene, our Anne (Anne-Marie) was born the 6th and baptised the 11th of January 1688 at Saint-Barthelemy-de-La-Rochelle. Her burial record of 1752 (P.A.T.) verifies that she was born in 1688/1689. Here is her baptism record:
