Meaning & origin

Cornellius is a rare variant of the ancient Roman name Cornelius, first recorded in the United States in 1974. Its peak year of use was 1977, though it has never reached the top 1000 names. The name's trajectory has remained stable at very low frequency, and no top states were recorded for it. For parents drawn to classical Roman names but seeking a slightly unconventional spelling, Cornellius offers a distinct choice that echoes the legacy of the Cornelian family.

Cornellius is a respelling or variant of the classical Latin name Cornelius, which was the name of a prominent Roman patrician family (gens Cornelia). The meaning is uncertain but often linked to the Latin word 'cornu' (horn) or 'corneus' (horn-colored). The variant spelling with double 'l' and 'ius' ending emerged in modern times, perhaps influenced by surnames like Cornell or as a creative respelling. It has seen occasional use in English-speaking countries since the 1970s.
