Combination of Joseph and Marion
A modern American blend likely created by combining the classic Hebrew name Joseph, meaning 'he will add', with the name Marion, a French diminutive of Mary. It follows the 21st-century trend of rhythmic, multi-syllabic invented names using the 'Jo-' prefix and '-marion' suffix.
