H BurghIn Bryan's Dictionary of Painters and Engravers (A-K). I (3rd ed.). London: George Bell & Sons., p.201 Burgh is described as an English engraver who worked in London in the 1750's. He worked principally for booksellers, and was chiefly employed for engraving portraits, among them is "Thomas Bradbury Minister of the Gospel," from his own design. From this entry we know therefore that Burgh was not only an engraver but was also capable of creating his own drawings.
