Pierre Larché was employed by Nicholas Denys, a persistent, if luckless entrepreneur who in 1650 had established a trading post at St. Pierre, Ile Royale, located beside the present day St. Peter's Canal, on Cape Breton Island. Larché had been married to an Adrianne Langlois, born abut 1640, but he was thought to have taken a Micmac wife when he was at St. Pierre. Larché died about 1668 in Miscou, New Brunswick
