Hi,
Jacques Fournier is mentioned as a child of Guillaume Fournier and M.F. Hebert born August 24th 1679 in Cyprien Tanguay's genealogical Dictionary. Tanguay read the act at the end of the 19th Century when the register was less deteriorated than it was when it was microfilmed, hence he could read more information than it is possible to read today. Anyway, this Jacques is not enumerated with this family in 1681, meaning he must have died soon after birth
