“ The Mercers’ Company is the first in precedence of the twelve great livery companies of the city of London, and is also the wealthiest both in trust and corporate property. The first charter was obtained in 1393, but the mercers appear to have been formed into a gild much earlier. Herbert finds the mercers as patrons of a charity a few years after 1172, and one Robert Searle, who was mayor in 1214, was a “mercer.” ”
