Saint Fidelis of Sigmaringen, O.F.M. Cap. (†1622) was a Capuchin friar who was a major figure in the Counter-Reformation and was murdered by his opponents at Seewis in Prättigau, now part of Switzerland. Fidelis was canonized in 1746. His Feast day is celebrated on April 24.
Saint Emiliana was one of three aunts of St. Gregory the Great. She lived with her sisters in their father's house, which was like a monastery, and encouraged one another to virtue through discourse and example. Her feast day is commemorated on January 5.
Saint Susanna of Rome (†295) was a Christian martyr of the Diocletianic Persecution. She was the daughter of Saint Gabinus of Rome and niece of Pope Caiuson. For her refusal to marry a pagan relative of Emperor Diocletian, she was arrested as a Christian. At the command of Diocletian, she was beheaded in her father's house, which was later turned by the Christians into a church. The church became known as Sancta Susanna ad duas domos. In addition to her main shrine in Rome, a church exists in Santiago de Compostela dedicated to her; it was first built in the early twelfth century after her relics were translated from Braga to Compostela. Susanna is venerated as the co-patron of the city. Her feast day is on 11 August in the Roman Martyrology, but since 1969 her veneration has been limited to the Church of Santa Susanna in Rome.
Saint Petronilla was an early Christian Saint who was identified in Rome as a supposed daughter of Saint Peter, probably because of her name and the great antiquity of her tomb. She appears in the legendary Acts of the martyrs Nereus and Achilleus and in the Liber Pontificalis, but as a virgin rather than as a martyr. She is venerated in Roman Catholic Church and her Feast is commemorated on May 31.
