Born , in
Amiens,
Picardy, Jean de Quen was about 17 years old when he joined the
Jesuits on 13 September 1620. He taught for three years at the Collège in
Eu and then left for
New France. He arrived in
Quebec City on 17 August 1635, where he taught at the College of Quebec, which opened the same year for
Franch and
First Nations boys. He taught there for two years before joining the
Sillery mission, an initiative aimed at educating the Native peoples. He later left the mission and went back to Quebec to minister to the Parish of Notre-Dame-de-la-Recouvrance. After a fire destroyed the school, chapel, and Jesuits’ residence in 1640, he resumed his service in Sillery and moved on to a
Trois-Rivières post, where he was involved in the establishing another mission. In 1640, he went back to Sillery and concerned himself with the hospital,
Hôtel-Dieu. There, he wore himself down but recovered quickly and was sent to the Trois-Rivières residence. He returned the following year to Sillery and was in charge of that mission centre for eight years (1642–1649). He fulfilled a very active ministry there, which brought him into contact with First Nations individuals from multiple locations, more particularly
Montagnais people,
whose language he learned with proficiency. ==Tadoussac==
