Saint Petronilla was an early Christian disciple who lived during the first or second century. While traditional accounts identify her as the daughter of the apostle Peter, modern research suggests she may have belonged to the Roman Aurelli family. She lived in Galilee before moving to Rome, where she eventually died. She is remembered as a virgin and a martyr, and her life is often associated with legends regarding her beauty and her connection to the apostolic lineage.
Life and identity


Though long considered the biological daughter of Peter, she might have been his spiritual daughter or a devoted follower. Some traditions claim Peter healed her of palsy. Other legends suggest she died following a hunger strike after being pursued by a pagan king named Flaccus. Historical evidence connects her to the Roman family of the Aurelli, which may explain her burial in the catacomb of Domitilla.
Veneration and legacy


Her remains were once housed in a mausoleum near Old St. Peter's, which later became a chapel and a burial site for French royalty. Due to her perceived relationship with Peter, she served as a patroness for the Frankish emperors. Today, her feast day is observed on May 31, and she is honored in the Catholic, Anglican, and Orthodox traditions.
