[1] In his "History and General Description of New France", Pierre-François-Xavier de Charlevoix gives three hypotheses for the origin of the name of the river.

As for the third, he could allude to a battle between the Algonquins and the Iroquois near the river, whose rotting bodies would have remained in place for a long time.

The name refers to the seigneury of Gentilly, granted to Michel Pelletier de La Prade in 1676.

It then crosses Soulard Lake and then takes a northwesterly direction to flow into the St. Lawrence River at Bécancour, eight kilometers west of Gentilly.

This park, which is located on the banks of the Gentilly River, straddles the territory of Sainte-Marie-de-Blandford and Bécancour.
