Combination of Lily (flower) and Anna (grace)
Lillyonna is a modern American compound name. It blends the floral imagery of the Lily with the classic Hebrew name Anna, which means grace or favor. This creative elaboration follows the trend of adding the 'onna' suffix to established names to create a more melodic, multi-syllabic sound.
