Possibly a variation of Mariah or a blend of Charity.
Chariah is a modern American invention, likely created as a rhythmic variation of the name Mariah or a diminutive form of Charity. It combines the 'Char-' prefix, associated with grace and kindness, with the popular '-iah' suffix found in many biblical names. Because it is a contemporary creation, it lacks a singular ancient etymology but carries the phonetic appeal of established classics.
