Gyllian

Gyllian is a feminine name that represents a variant spelling of Gillian, which itself derives from the medieval English name Juliana, a feminine form of Julian (ultimately from the Roman name Julius). The distinctive spelling with a 'y' gives the name a more unique or stylized appearance while maintaining the traditional pronunciation. Gillian/Gyllian means "youthful" or "downy-haired youth" in its Latin origins. This name gained some popularity in the United Kingdom before spreading to other English-speaking countries. While not among the most common names, it offers a balance between familiarity and uniqueness. The variant spelling Gyllian remains considerably rarer than the standard Gillian, making it an attractive choice for parents seeking a recognizable name with a distinctive presentation.

Pronounced GIL-yuhn.

As of October 2026, Gyllian ranked #17957 in US births in 2010 SSA, peaked at #12519 in 2001.
