Modern invented name, likely combining elements of Trevor and Darius.
Trevarius is a contemporary American coinage. It likely blends the Welsh-rooted Trevor, meaning 'from the large settlement,' with the Latinized Persian name Darius, meaning 'possessing goodness' or 'kingly.' The suffix '-arius' adds a rhythmic, classical flair common in modern creative naming.
