Unknown; possibly a modern variation of Nona or Nyanya
Nyonna is a rare modern name with an unclear etymology. It may be a creative variation of the Latin name Nona, meaning 'ninth', or influenced by the Swahili term Nyanya, meaning 'grandmother'. In contemporary American usage, it is often chosen for its melodic sound rather than a specific historical lineage.
