Gylliane is in Origin.

Gylliane blends the medieval English Gillian with the French Juliane pattern, ultimately tracing to Latin Iuliana, the feminine of Iulianus (“of the Julian family”) derived from Iulius. The traditional meaning is linked to the ancient Roman gens Julia and is commonly glossed as “youthful” or “downy‑bearded.” The -iane ending and the doubled l evoke French orthography, while the initial Gy- marks it as a modern, stylized spelling.

In use, the root name (Gillian/Jillian) was widespread in medieval England, declined after the 17th century, and revived in the 20th, especially in the Anglophone world. Gylliane itself is a rare late‑20th/early‑21st‑century variant adopted for distinctiveness, occasionally seen in Francophone settings alongside forms like Gyliane or Gilliane. Related variants include Gillian, Jillian, Juliane, Juliana, Giuliana, and French Julienne; short forms may be Jill, Gilly, Lia, or Liane.
