Dominican Nuns of the Perpetual Rosary

The Dominican Nuns of the Perpetual Rosary are a religious institute founded in 1880 in Calais, France, by Father Damien-Marie Saintourens, Mother Rose of Saint Mary Werhle and Mother Mary Imelda Gauthier, all of them from the Order of the Preachers (Dominican Order). The nuns of the Order of Preachers, known as Dominican, came into being when Saint Dominic of Guzmán gathered Albigensian women converts to the Catholic Faith in the Monastery of Our Lady of Prouille, France, in 1206.
