Maria Domenica Brun Barbantini was an Italian religious sister born in 1789 in Lucca. After experiencing the loss of her husband and her young son, she dedicated herself to the service of the suffering. She established the Camillian Sisters Ministers of the Sick in 1829, an order focused on caring for the ill and frail. Throughout her life, she personally sought out abandoned and sick women in the streets of Lucca, transforming her personal grief into a lifelong mission of charity and nursing.
