Kemoimenahan
Kemôimenahan was an Abenaki name for the island also known in French as Île aux Prunes, in the Saint Lawrence near Verchères. The Indigenous name means the island of lice.
The island later became part of the Verchères estate. On 3 November 1672, Intendant Jean Talon granted François Jarret de Verchères a riverfront fief with seigneurial and judicial rights. The original grant measured half a league in frontage and one league in depth; it was subsequently enlarged to include Île aux Prunes, Île Longue and additional land inland. Jarret had come to New France with the Carignan-Salières regiment and remained after its recall to France. His estate belonged to the colonial effort to settle former soldiers along the river.
