Filles de la Sagesse
During his episcopate, Loughlin founded 120 parishes. Plans to build the larger Cathedral of the Immaculate Conception were deferred in favor of orphanages, schools, and hospitals. He was succeeded in 1892, by Bishop Charles Edward McDonnell, former chancellor of the Roman Catholic Archdiocese of New York. The Roman Catholic Diocese of Brooklyn served at that time 250,000 Catholics. With the increase in the number of immigrants of various nationalities, McDonnell founded a number of national churches which ministered to parishioners in their own language. To this end, he invited several religious institutes into the diocese, including the Redemptorists, Benedictines, Franciscans (including the Minor Conventuals and Capuchins), Jesuits, Sisters of the Holy Family of Nazareth, Missionary Sisters of the Sacred Heart, Daughters of Wisdom, and Sisters of the Holy Infant Jesus. He also built three hospitals. Camp Wycoff and Camp Black, set up during the Spanish–American War were attended by local clergy.
