Further to the untimely death of the sickly first Mother General, Karska, in 1860, on January 17, 1863, Pope Pius IX granted her successor, Darowska, the right to move the headquarters of the congregation to Jazłowiec, in the Western Austrian-occupied part of her native Podolian region of Poland, in the Roman Catholic Archdiocese of Lviv, where she received the charitable gift of an estate.

[2] The original rule was revised in 1872 by Darowska, which highlighted the specificities of the congregation.

Pius IX granted the Sisters of the Immaculate Conception a decretum laudis on May 22, 1863, and approved the congregation on July 29, 1874.

The Sisters of the Immaculate Conception dedicate themselves to the Christian education of youth, especially girls and young women, and to parish work.

[3] The order is headquartered in Szymanów, where the sisters are custodians of the shrine to Our Lady of Jazłowiec.
