Jill

Jill is an English feminine given name, a short form of the name Gillian and Ghislaine, which in turn originated as a Middle English variant of Juliana. Jill was such a common name that it had an everygirl quality, as in the 15th century English nursery rhyme Jack and Jill. By the 1600s, the name had become a term for a "common street jade," implying promiscuous sexual behavior, and declined in usage in the Anglosphere. Usage of the name increased again in the 20th century. The name was most used in English-speaking countries from the 1930s to the 1970s. It is currently well-used in the Netherlands.
