Marcellina
b. circa 330/335, Rome; d. 398, Milan
Marcellina, sister of Saint Ambrose, chose a life of chastity and asceticism, moving from Rome to Milan when her brother became bishop of that city. In 353, while still in Rome, she received the veil of virginity from Pope Liberius along with advice about her duties in preserving virginal purity. She died in Milan in 398 and her feast day is recognized by the Catholic Church on July 17 each year.
