Meaning and origin of Cornelius
Cornelius is often said to mean “uncertain; possibly 'horn'”; the origin is uncertain, though it is usually linked to Latin roots.
Cornelius comes from the Roman family name Cornelia, one of the great patrician clans of ancient Rome. Its origin is uncertain; it is often linked to the Latin cornu, 'horn', but this is not proven. In the New Testament Cornelius is a centurion described as one of the first gentile converts to Christianity, and the name was later carried by saints and a pope. Businessman Cornelius Vanderbilt gave it American prominence. Neil, Con and Corey are nicknames.
