Cheerful, youthful, or soft-haired
Joliana is a modern elaboration, likely created by blending the French-derived 'Jolie' (meaning pretty) or the English 'Jolly' with the suffix '-iana'. It may also be interpreted as a variant of Juliana, which stems from the Roman family name Julius, associated with youthfulness.
