"Jill" is a post mill originally built in Dyke Road, Brighton, in 1821. It was known as "Lashmar's New Mill" and was built to replace "Lashmar's Old Mill". In 1830, the Windshaft broke, bringing the sails crashing to the ground. A painting by Nash dated 1839 and an engraving in the "Handbook to Brighton" (1847) show her to have had a roof mounted Fantail, similar to the arrangement still found on Icklesham windmill. "Lashmar's New Mill" was the most southerly of the three Dyke Road post mills. In 1852 she was moved to Clayton by a team of horses and oxen. The site is now Belmont—a short street of Grade II-listed villas.
