She arrived at Saint-Basile in 1874, and twenty years later, her sister Élisabeth entered the same community and took the name Saint-Stanislas (1871-1912). Father Thériault was a Dominican and parish priest in Ottawa. In July 1914, he came to Saint Basile to preach a spiritual retreat to the Religious Hospitallers.
