M. Tullius Cicero Pro A. Cluentio 21

[21]
  There was a woman of Larinum , named Dinea, the mother-in-law of Oppianicus, who had three sons, Marcus Aurius, Numerius Aurius, and Cnaeus Magius, and one daughter, Magia, who was married to Oppianicus. Marcus Aurius, quite a young man, having been taken prisoner in the social war at Asculum , fell into the hands of Quintus Sergius, a senator, who was convicted of assassination, and was put by him in his slaves' prison. But Numerius Aurius, his brother, died, and left Cnaeus Magius, his brother, his heir. Afterwards, Magia, the wife of Oppianicus, died; and last of all, that one who was the last of the sons of Dinea, Cnaeus Magius, also died. He left as his heir that young Oppianicus, the son of his sister, and enjoined that he should share the inheritance with his mother Dinea. In the meantime an informant comes to Dinea, (a man neither of obscure rank, nor uncertain as to the truth of his news,) to tell her that her son Marcus Aurius is alive, and is in the territory of Gaul , in slavery.
