Unknown; possibly a modern variation of Ayanna or Iona.
Ayonna is a modern American name with ambiguous roots. It is often considered a creative variation of Ayanna, which is frequently attributed to East African origins meaning 'beautiful flower,' or it may be a phonetic elaboration of Iona, a Scottish island name. Due to its rare usage, it lacks a singular established etymology.
