A cloistered contemplative order, founded at Saint Hyacinthe, Canada in 1861 by Aurelie Caouette, in religion Mother Catherine-Gurelie of the Precious Blood, with the cooperation of Monsignor Joseph La Rocque. The sisters maintain perpetual adoration of the Blessed Sacrament and conduct retreats. The institute subsists on alms and the dowries of choir sisters. Each convent has its own novitiate and is independent in government, but new foundations are made from the mother-house at Saint Hyacinthe. The order has houses in Canada, the United States, Cuba, Italy, and China.
