The François Perrault who died in 1745 per that funeral was around 67 year old merchant who died in hospital in Trois-Rivières and was buried in the hospital's poor cemetery. He died of illness which kept him unconscious.
The Biographi.ca link you have is for the man who died in Trois-Rivières described above. Nothing to do with the profile you have linked. Wrong wife for one.
There are various links you have there, Denis Beauregard of Francogene errs in putting the 1745 date for your linked man. The rest give either no data, are membership items, or give a vague date of 1704 in Bécancour. Can't find a record of such so far, Bécancour parish registers only open in 1716. Jetté makes no mention of their deaths.
Anyways, detached the ''son'' who didn't belong with them.
