I have disconnected her from Pierre-Charles Gingras. No one seems to know if she even was married.
The error I suspect came from l'Abbé Tanguay whose momental genealogy study contained few errors, ... but this is one.
There was a Marie Anne Bélanger daughter of Charles and Madeleine Jobidon who married à Pierre Gingras in 1740-11-21 in an unknown place the brother of Pierre CHARLES Gingras, thus she too will be disconnected from Charles Gingras after being correctly to her real husband Pierre.
This error is simply due to the confusion of their first names (;pierre CHARLES b-1710 and simply PIERRE b -1711). They both had a lot of children over a significant peroide of time.
I base the above upon info from the PRDH which is an elaborate update of Tanguay's work, so to speak, by the University of Montréal.
I hope this will explain and clear up things a little.
