The Story of Jillian

Jillian is a medieval variant of Gillian, itself a form of Juliana, the feminine of Julian. The name derives from the Latin 'Julianus,' connected to the Roman family name Julius, which may come from the Greek 'ioulos' (downy-bearded, thus youthful). Julius Caesar's family bore this name, and through Saint Julian and Saint Juliana, it spread throughout medieval Christian Europe.

Jillian peaked in the United States in the 1980s-1990s, appealing as a more distinctive alternative to the extremely popular Jill. It has slowly declined since then as naming tastes shifted toward less common vintage names.

Gillian of ancient Nursery Rhyme fame ('Jack and Jill' may derive from 'Jack and Gill/Gillian') gives the name a folkloric British dimension. In Celtic Ireland, the form Sile (Sheila) is the Irish equivalent, giving it connections to Irish Catholic naming traditions.
