Blessed Maria Angela Siedliska (†1902), known as Mary of Jesus the Good Shepherd, was a Polish Catholic nun who founded the Congregation of the Sisters of the Holy Family of Nazareth. She felt a religious calling early, entering a Franciscan monastery in 1870. In 1873, she established her congregation to serve families and the poor, emphasizing education and charity. She led with humility, enduring personal hardships while spreading her mission to Europe and America. She was beatified in 1989, and her feast day is celebrated on June 10.
