Romilius

Romilius is a Roman family name (nomen gentilicium) derived from the mythological name Romulus. According to tradition, the Romilii claimed descent from Romulus, the legendary founder and first king of Rome, their name being formed by adding the diminutive suffix -ilius to the original cognomen.

Etymology

The nomen Romilius belongs to a large class of Roman gentilicia formed with the suffix -ilius, which were typically derived from surnames ending with the diminutive suffix -ulus. The Roma root refers to the Latin name of Rome, Rōma, but the derivative Romulus connects the founder myth directly to the city. Scholars note that while the legend says Romulus gave his name to Rome, the linguistic evidence suggests the reverse — that Romulus is a back-formation from Roma.

Historical prominence

The Romilia gens was a minor patrician family at ancient Rome during the period of the monarchy and early Republic. Its most notable member was Titus Romilius Rocus Vaticanus, who served as consul in 455 BC and later, in 451 BC, became one of the Decemviri legibus scribundis — the ten men appointed to codify Roman law in the Twelve Tables. After the Decemvirate era, the Romilii receded from recorded history, re-emerging only sporadically in imperial times. However, inscriptions attest to members bearing the nomen across several centuries.

Usage and variants

The name has seen rare revival as a given name, possibly in tribute to its ancient lineage, but it remains a masculine first name outside common use.
