About the publisher:
George Grierson (1680 - October 27, 1753) was an Irish printer and publisher. He operated as the 'Kings Printer" from 1732 to 1753, It is interesting to note that Grierson was the only printer in Dublin allowed to print Holy Bibles. Following his death in 1753, son, Boulter (1737-1771) , took over the family business, which lasted well into the 19th century.
