Lily flower or God is my oath
Lillyen is a modern creative spelling that blends the floral imagery of Lily with the suffix structure of names like Lillian or Ellen. It primarily derives from the Latin 'lilium' for the flower, but can also be viewed as a variant of Lillian, which stems from Elizabeth, meaning 'God is my oath'.
