Kornylo / Cornelius / Kornel / Korneliusz / Cornelio

Kornylo is the Ukrainian form of the Roman family name Cornelius. The name Cornelius itself is derived from the Latin cognomen Cornelius, which is thought to come from the Latin word 'cornu', meaning 'horn'. This name was notably borne by a prominent Roman gens (clan), the Cornelia, which produced many important figures in Roman history, including several consuls and generals.

In a Christian context, Saint Cornelius was a 3rd-century Pope, martyred in 253 AD. His veneration helped to popularize the name throughout Europe, particularly in Catholic and Orthodox countries. The Ukrainian form Kornylo emerged through linguistic evolution, adapting the Latin root to Slavic phonology and morphology.
