Tremellia gens

The gens Tremellia was a minor plebeian family at ancient Rome. Members of this gens are first mentioned towards the end of the Second Punic War, but the highest rank ever attained by any of the Tremellii under the Republic was that of praetor. After falling into obscurity during the first century BC, the fortunes of this family briefly revived under the Empire, when Gnaeus Tremellius was appointed consul suffectus in AD 21, during the reign of Tiberius.

Praenomina
The main praenomen of the Tremellii who rose to prominence in the Roman state was Gnaeus, although a few bore other names, including Gaius and Lucius.

Branches and cognomina
The only cognomina borne by any of the Tremellii mentioned in history are Scrofa and Flaccus. Scrofa refers to a sow with piglets, and belongs to a large class of surnames derived from creatures and everyday objects. This cognomen was handed down through one branch of the Tremellii for a century, and Varro relates the story of how Lucius Tremellius Scrofa, quaestor in 143 BC, when attacked by the enemy, vowed to scatter them like a sow scattering her piglets, thereby obtaining his surname. Flaccus seems to have been a personal surname, as it is borne by only one of the Tremellii; it originally designated someone with prominent or floppy ears, and belongs to a large class of cognomina derived from someone's physical features.

Members

 * Gnaeus Tremellius Flaccus, an ex-quaestor, was one of five ambassadors sent to Attalus I, the king of Pergamum, in 205 BC to bring back a sacred stone, representing the Magna Mater. In 203 he was one of the plebeian aediles, and the following year he became praetor, receiving the province of Sicily.
 * Gaius Tremellius, praetor in an uncertain year, likely 175, 174, or 170 BC. In 173, he was one of the decemvirs chosen to divide lands in Liguria and Cisalpine Gaul between the Romans and their Latin allies.
 * Gnaeus Tremellius, as tribune of the plebs in 168 BC, blocked a measure to extend the terms of the censors. While he was praetor in 159, he was fined for insulting the Pontifex Maximus.
 * Gnaeus Tremellius, consul suffectus in AD 21, might have been a descendant of Gnaeus Tremellius Scrofa, the friend of Varro.

Tremellii Scrofae

 * Lucius Tremellius Scrofa, quaestor in 143 BC, served under Aulus Licinius Nerva, the governor of Macedonia, and put down a revolt. Scrofa likewise served as praetor, some time prior to 135 BC.
 * Tremellius Scrofa, quaestor in 71 BC, served under Crassus in the Third Servile War, and was wounded while giving chase to Spartacus.
 * Gnaeus Tremellius Scrofa, a friend of Varro of Atticus, was probably the same Gnaeus Tremellius who was one of the judges at the trial of Verres in 70 BC, and a military tribune the following year. He later served under Caesar in the Gallic Wars, and was praetor in an uncertain year.
 * Tremellius (Cn. f.) Scrofa, the son of Varro's friend, mentioned by Cicero in 45 BC.
