Joseph Edmondson, 1732-1786, originally apprenticed as a barber but became a heraldic artist and eventually, in 1763, became Queen Charlotte's coach-painter. Though he continued his coach-painting business til his death, Edmondson began publishing his "Baronagium Genealogicum" and became a Mowbray Herald of Arms Extraordinary in 1764.
Edmondson was well received by aristocratic patrons because of his enthusiasm and talent but disliked by academic peers because of his humble beginnings and heritage but also his pushy and intrusive personality. His many publications include "Tables of Precedency" (1764), "Historical and Genealogical Account of the Noble Family of Greville" (1766), "Companion to the Peerage of Great Britain and Ireland" (1776), and his most famous work, "A Complete Body of Heraldry" (1780).
