Нума Помпилий
The Oscan cognate of Quintus was "Pompo", a name best known from the father of Numa Pompilius, the second king of Rome. The gentes Pompilia and Pomponia (both of which claimed descent from Numa Pompilius) were derived from this praenomen. The nomen Pompeius may also be a patronymic based on the name Pompo.
