Born Cornelia Peacock in
Philadelphia, she was raised a
Presbyterian. In 1831, she married Pierce Connelly, an Episcopal priest. They converted to Catholicism in 1835 and separated in 1844, when her husband decided to become a Catholic priest. Cornelia was invited to England to educate girls. There she drew up a set of rules for a new religious congregation, which she called the "Society of the Holy Child Jesus". Bishop
Nicholas Wiseman sent her to a convent at
St Mary's Church, Derby, where she was soon running a day school for 200 students and training
novices for her new institute. In December 1847, she took her perpetual vows as a religious sister and was formally installed as superior general of the society. In 1848, Wiseman, unable to meet expenses connected with the schools, had Cornelia relocate to his district at
St. Leonard's-on-Sea in Sussex. The Society was approved in 1887 by
Pope Leo XIII, and the rules and constitutions were confirmed and ratified by him in 1893. ==Expansion==
