According to the Wikipedia:
"Saints Chrysanthus and Daria (3rd century - c. 283) are saints of the Early Christian period. According to legend, Chrysanthus was the only son of an Egyptian patrician, named Polemius or Poleon, who lived during the reign of Numerian. His father moved from Alexandria to Rome. Chrysanthus was educated in the finest manner of the era. Disenchanted with the excess in the Roman world, he began reading the Acts of the Apostles.
He was then baptized and educated in Christian thinking by a priest named Carpophorus. His father was unhappy with Chrysanthus's conversion, and attempted to inculcate secular ways into his son by tempting him with prostitutes, but Chrysanthus retained his virginity.
He objected when his father arranged a marriage to Daria, a Roman Vestal Virgin. Chrysanthus converted his new bride and convinced her to live with him in a chaste state. Since Vestal Virgins take a vow of chastity during their 30-year term of service Daria's agreement to live in a chaste marriage would not be surprising.
They went on to convert a number of Romans. When this illegal act was made known to Claudius, the tribune, Chrysanthus was arrested and tortured. Chrysanthus's faith and fortitude under torture were so impressive to Claudius that he and his wife, Hilaria, two sons named Maurus and Jason, and seventy of his soldiers became Christians. For this betrayal, the emperor had Claudius drowned, his sons beheaded and his wife went to the gallows. Daria was sent to live as a prostitute, but her chastity was defended by a lioness. She was brought before Numerian and ordered to be executed by stoning and then burial alive in a deep pit beside her husband. They were entombed in a sand pit near the Via Salaria Nova, the catacombs in Rome."
