Baby will be forever young with the name Gyllian. Typically given to girls, Gyllian is a version of Gillian with Medieval English origins. It has many supposed meanings, like “youthful” or “youth” from the Late Latin Iūlius and “downy-bearded,” stemming from ioulos in Greek. Gyllian also finds ties with the Roman god of the sky and thunder, Jupiter. Your little rascal will be full of the joys of youth, always playing with friends and wondering about life around them. Encourage baby to see the silly side even as they grow older with the refreshing choice, Gyllian.
