Free Brother A Free Brother is one of the various levels of membership to the Worshipful Company of Clockmakers or any other guild, such as the Blacksmiths' and Goldsmiths’ Companies. Prospective members paid a fee to become a Free Brother, and the Company would write to the Guildhall requesting permission to make the prospective member a Freeman of the city. If granted freedom to the Clockmakers’ Company, the clockmaker would then be allowed to sell clocks in the City of London.
