There are 2 couples named Jean Nolet / Nollet - Marie Marcoux.
The first is Jean Marie Nolet married with Marie Élisabeth Marcoux in 1786. She is only called Marie Élisabeth on the first 2 records in their marriage, after that only Marie, except once Marie Isabelle.
The second is Jean Baptiste Nolet married with Marie Claire Marcoux in 1814. She gets called Marie Claire on records, consistently.
Jean Marie Nolet died in 1840 at ''83'', the record lists him under Joseph and names his wife Catherine. (No other such couple exists). Records subsequent to his death, including 2 marriages of his children and his wife Marie's funeral in 1843, name him Joseph. Who knows why? But this is definitely the first couple.
So yes, the Magloire linked is the wrong guy, simplest way to correct is to attach him to the correct parents, that way spouse and children don't need changing.
