Nomen gentilicium in the context of "Julii"

The gens Julia was one of the most prominent patrician families of ancient Rome. From the early decades of the Republic, members of this gens served in the highest offices of the Roman state, beginning with Gaius Julius Iulus, consul in 489 BC. However, the Julii are perhaps best known for Gaius Julius Caesar, the dictator and adoptive father of the emperor Augustus, through whom the name was passed to the Julio-Claudian dynasty of the first century AD. The nomen Julius became very common in imperial times, as the descendants of persons enrolled as citizens under the early emperors began to make their mark in history.

The gens Quinctia, sometimes written Quintia, was a patrician family at ancient Rome. Throughout the history of the Republic, its members often held the highest offices of the state, and it produced some men of importance even during the imperial period. For the first forty years after the expulsion of the kings the Quinctii are not mentioned, and the first of the gens who obtained the consulship was Titus Quinctius Capitolinus Barbatus in 471 BC; but from that year their name constantly appears in the Fasti consulares.

As with other patrician families, in later times there were also plebeian Quinctii. Some of these may have been the descendants of freedmen of the gens, or of patrician Quinctii who had voluntarily gone over to the plebs. There may also have been unrelated persons who happened to share the same nomen.

A cognomen (Latin: [kɔŋˈnoːmɛn]; pl.: cognomina; from co- "together with" and (g)nomen "name") was the third name of a citizen of ancient Rome, under Roman naming conventions. Initially, it was a nickname, but lost that purpose when it became hereditary. Hereditary cognomina were used to augment the second name, the nomen gentilicium (the family name, or clan name), in order to identify a particular branch within a family or family within a clan. The term has also taken on other contemporary meanings.

Pacatianus, known in English as Pacatian (/ˈpəkeɪʃ(i)ən/; Latin: Tiberius Claudius Mar[...] Pacatianus; died c. 248) was a usurper in the Danube area of the Roman Empire during the time of Philip the Arab. His praenomen and nomen suggest his ancestors obtained Roman citizenship either during the time of Tiberius or of Claudius.

His life is known from mentions in the histories of Zosimus and Zonaras. However, the chronology of these accounts is obscure, and modern scholars use coinage to establish the timeline of his life and revolt. Zonaras names him as a 'unit commander' of one of the Danube legions, possibly Legio VII Claudia. He was likely a leader in the effort to drive Gothic invaders out of Roman territory in 248, one of the first actions of the Gothic War. Either during this action or soon after he was acclaimed emperor by the Danube legions. Eventually his control extended to the city of Viminacium. According to Zosimus, the news of Pacatian's revolt in Moesia and of Jotapian's near-simultaneous revolt in Syria prompted Philip to make an offer to the Roman Senate to step down. Both Zosimus and Zonoras relate that Philip was advised by the senator Decius, who predicted that Pacatian would soon be killed by his troops. This soon came to pass, and Philip (over Decius' objections) sent Decius to the Danube to find out the causes of the revolt. Decius was promptly acclaimed as emperor by the legions on the Danube, and (though Zonaras records that Decius offered to resign) eventually overcame Philip by the end of 249.

The gens Abronia was an obscure plebeian family at ancient Rome. The only members of this gens mentioned by Roman writers are Abronius Silo, a Latin poet during the time of Augustus, and his son, who was the author of pantomimes. Epigraphic sources provide a few other instances of this nomen, but the readings are very uncertain, and it is possible that Abronius is merely an orthographic variation of Apronius.
