St. Domitilla (Flavia Domitilla) was a Christian Roman matron of the imperial family who lived at the end of the first century. She was grand-daughter of Emperor Vespasian, niece of Emperors Titus and Domitian. She was married to Titus Flavius Clemens, a Roman consul, nephew of Emperor Vespasian, and the first cousin of Emperors Titus and Domitian. She and her husband were converted to Christianity. On the land, which belonged to Flavia Domitilla, is the catacomb of Domitilla, "Coemeterium Domitillae", one of early Christian cemeteries. As a result of accusations her husband was martyred in 96 AD, and Flavia Domitilla was banished to the Island of Pandataria in the Tyrrhenian Sea, where she was possibly put to death.
