The Greenhills were a prolific family of clockmakers, gunsmiths and locksmiths and amongst their number were some of finest artisans working in Kent in the 17th century. It is probable that the present clock is by the third John Greenhill, who is thought to have been born circa 1655. He became a member of the Corporation of Maidstone and owned a substantial number of properties. In 1687 he and other council members were expelled from the Corporation by order of James II, but he subsequently served on the council again and in 1702 was elected Mayor of Maidstone. Upon his death in 1712 he left an extensive will and was presumably very wealthy. See Michael Pearson, Kent Clocks and Clockmakers, pp.67-84.
