Thomas Jefferys (c. 1719 – 1771), "Geographer to King George III", was an English cartographer who was the leading map supplier of his day.
[2] As "Geographer to the Prince of Wales", he produced A Plan of all the Houses, destroyed & damaged by the Great Fire, which began in Exchange Alley Cornhill, on Friday March 25, 1748.
[1] In 1754, Jefferys published a Map of the Most Inhabited Part of Virginia which had been surveyed by Joshua Fry and Peter Jefferson in 1751.
In 1754, Jefferys took a robust and public stance in the controversy with the French on the boundary of Nova Scotia and Acadia, which arose in the time and context of Father Le Loutre's War, which is commonly held to have begun in 1749 and ended with the expulsion of the Acadians in 1755.
These were large-scale maps with several sheets for each county; in the case of Bedfordshire and Huntingdonshire the scale was two inches to one mile (1:31680).
