Who were Cicero's siblings?

Virgil was born of a humble family.

His father is without a name and his occupation is uncertain but he is some form of Laborer, and mostly stated as either a farmer or potter, sometimes a forester and dealer in lumber.

His father was working for a certain Magius (who is Virgil's Grandfather), and Magius allow him to marry his daughter, Magia (who is Virgil's Mother).

Legend has it that when Virgil was in the womb, his mother dreamed that she gave birth to a laurel branch that, once planted, sprung immediately from the earth, and within moments became a tree heavily laden with fruit and flowers. The next day, when she was on her way to a neighboring part of the country with her husband, she turned aside and gave birht to her child in a ditch beside the road. Virgil did not cry at death, and had such a gentle expression as even then to give assurance of an unusually happy destiny.

Virgil was born on October 15, 70 B.C.E., at Andes near Mantua in Cisalpine Gaul (modern Mantova, 20 to 25 miles southwest of Verona, Italy).
