In 1843, under the guidance of Bishop Ignace Bourget, Eulalie Durocher, her good friend Mélodie Dufresne and well-known teacher, Henriette Céré, founded the Congregation of the Holy Names of Jesus and Mary (SNJM) in Longueuil, Quebec.
This Congregation is devoted to the education of youth. At the time of Mother Marie-Rose’s premature death in 1849, four educational institutions had already been established: Longueuil, Beloeil, Saint-Timothée and Saint-Lin.
After her death, the Sisters of the Holy Names of Jesus and Mary continued to establish and administer numerous public and private institutions.
Today, the religious community numbers 1100 Sisters and 600 Associates in Canada, the United states, Africa (Lesotho,) Brazil and Peru. They work in the areas of education, social justice, full development of the human person, the promotion of the arts and pastoral ministries. They are also involved in various international organizations.
