Jilly is in Origin.

Jilly is an English affectionate diminutive of Jill, itself a medieval short form of Gillian, which traces back to the Latin Juliana (Iuliana), the feminine of Julian from Julius. Through this chain the name carries the traditional meanings “youthful” and “soft‑haired/downy,” reflecting the Latin/Greek root ioulos for soft, first growth. While long used as a pet name within families and friends, Jilly began appearing on birth records as an independent given name in the mid‑20th century alongside the boom of Jill and Gillian in English‑speaking countries.

Usage has been most visible in Britain - helped by the popularity of British writer Jilly Cooper - though it remains comparatively rare and informal in the United States. Spelling variants include Jillie and Jilli; closely related forms are Jill, Gill, Gillian, Juliana, Julia, and Julianne, with Julian as the masculine counterpart. Jilly’s breezy, upbeat sound keeps it appealing as a cheerful nickname or a lively standalone choice.
