Ariya is a modern variant that may belong either to the Aria family or the Arya family, depending on the route a parent has in mind. In practice, that means the meaning can differ slightly from one usage to another.
The spelling Ariya fits a broader modern trend of adapting popular vowel-rich names into fresh forms. Because the source links it to more than one root name, it is best published as a flexible variant rather than forced into one fixed origin.
