Teresa Manganiello (1 January 1849 – 4 November 1876) was an Italian who became a member of the Secular Franciscan Order.
Pope Pius IX received her in a private audience in 1873 and blessed her for her mission which was to establish a new religious congregation.
Manganiello died of a sudden illness in late 1876 before she could accomplish this task but her work soon led to the establishment of the Franciscan Immaculate Sisters that Father Ludovico Acernese founded.
[1] The cause for beatification commenced on 23 April 1991 with the declaration of "nihil obstat" under Pope John Paul II which granted her the title of Servant of God.
The Positio was submitted to the Congregation for the Causes of Saints in 1999 which culminated with the declaration of her life of heroic virtue on 3 July 2009.
