Father of a family without a fortune or political influence, founder of a community of Daughters Hospitallers and founder of the city of Montreal, Jerome remains the great unknown.

Unknown because he was unable to leave France to come to America due to family and professional responsibilities.  He remained in the shadow of Paul Chomedey de Maisonneuve and Jeanne Mance whom he chose to collaborate in the implementation of his “visionary” project.

Jerome was born in La Fleche, France March 18, 1597.  He pursued his studies at the Jesuit College of this city.  When his father died in 1619, Jerome succeeded him as tax collector.  He was married to Jeanne de Bauge who bore him five children.
