Their story
Susanna was nobly born in Rome and is said to have been a niece of Pope Caius. She had vowed her virginity to God and refused to marry. For this she was denounced as a Christian and suffered a cruel martyrdom about 295, early in Diocletian's (Roman emperor 284–305, who launched the last and fiercest persecution of Christians in 303) reign.
Butler states that no genuine acts of her life survive, but she is named in many ancient martyrologies. The church in Rome that bears her name had been one of the city's parish churches since the fifth century.
