What is "sextilia"

Sextilia (c. 5 - 69) was the mother of Lucius Vitellius the Younger and Aulus Vitellius.

The gens Sextilia was a plebeian family at Rome. The first member of the gens to achieve prominence was Gaius Sextilius, consular tribune in 379 BC. None of the family obtained the consulship, but they endured throughout Roman history from the early Republic into imperial times.
