Modern invented name, likely a blend of Jar- and Octavious.
Jartavious is a contemporary American name created by combining the popular prefix 'Jar-' (as seen in Jarius or Jarmaine) with the suffix '-tavious' from the Latin name Octavius. While it does not have an ancient etymology, it follows the rhythmic patterns of modern African-American naming traditions.
