Little biographical information about her exists. Her native place is sometimes given as Sicily, sometimes as Rome. She had, besides Gregory, a second son.
Silvia was portrayed sitting with the face, in which the wrinkles of age could not hide the beauty, in full view.
The eyes were large and blue, and the expression was gracious and animated. The veneration of Saint Silvia is of early date.
Silvia had built a chapel in her house. In 645, the monks from the monastery of March Saba (Palestine) settled in this house, and devoted it to the celebration of Saint Sabas.
In the 9th century an oratory was erected over her former dwelling, near the Basilica of San Saba.
Pope Clement VIII (1592–1605) inserted her name under 3 November in the Roman Martyrology. She is invoked by pregnant women for a safe delivery.
