Twenty years after Pope Pius IX's Apostolic Constitution, "Ineffabilis Deus", the Archdiocese of New Orleans's second indigenous religious congregation of women was founded, as the Sisters of the Immaculate Conception. They were founded in Labadieville, Louisiana, by the French-born Reverend Cyprien Venissat and Miss Adelaide Elvina Vienne. A former school-teacher, she took the veil (as Mother Mary of the Immaculate Conception, CIC) from the Most Reverend Napoléon-Joseph Perché, on 11 July 1874. Mother Mary died in 1885, at the age of 48.
