Marie-Rosalie Cadron-Jetté was a 19th-century Canadian midwife and nun who dedicated her life to supporting unwed mothers. Born in Lavaltrie, Quebec, she lived as a widow in Montreal after her husband died of cholera in 1832. Working alongside Bishop Ignace Bourget, she provided refuge and care to women facing social stigma. This mission led her to establish the Congregation of the Sisters of Misericorde in 1848, an institute specifically created to assist struggling mothers and their children.
