Orbilia gens

The gens Orbilia was an obscure plebeian family of ancient Rome. None of its members are known to have held any magistracies. Its most famous representative may have been the grammarian Lucius Orbilius Pupillus, who operated a school at Rome, and was the master of Horace.

Origin
The nomen Orbilius belongs to a class of gentilicia formed from other names, in this instance the Latin nomen Orbius, using the diminutive suffix -ilius. Orbius is derived from the cognomen Orbus, a waif or orphan.
