Sennia gens

The gens Sennia was an obscure plebeian family at ancient Rome. Few members of this gens are mentioned in history, but others are known from inscriptions.

Origin
A large majority of the Sennii are known from inscriptions from various parts of Gaul, suggesting that the family was of Gallic origin.

Praenomina
The main praenomina of the Sennii were Lucius, Gaius, and Marcus, the three most common names throughout all periods of Roman history. Less frequently the Sennii employed a variety of other common praenomina, including Titus, Quintus, Sextus, and Decimus.

Members
