The first Glasgow directory was published in 1783 by John Tait. This image is taken from a facsimile reprint published in 1871 by Robert Forrester. Page 45 includes surnames from Murdoch to McDonald.
Angus McDonald was a Highlander whose shop dealt in silver plate, hardware, toys, tea, and “alternative” medicines including his famous "Balm of Gilead." He kept a shopman or porter named Murdoch McDonald who, according to the advertisements, had been cured of every disease known to humanity by the liberal use of his master's drugs.
