Pompiliusz / Pompilius

Pompiliusz is the Polish form of the Roman nomen (family name) Pompilius. The Roman gens Pompilia was an ancient plebeian family, though its most famous member, Numa Pompilius, was traditionally the second king of Rome. The name's etymology is believed to derive from the Latin 'pompeius' or 'pompeius' meaning 'fifth', suggesting it may have been given to a fifth-born child or a child born in the fifth month.

While not widely used, the name has a strong historical and classical resonance due to its association with early Roman history. Its usage is primarily confined to Poland, where it maintains its Latin root and classical sound. It is a rare name, often chosen for its unique historical connection.
