Derivatives

   Later mapmakers relied on the Fry-Jefferson map to create new maps of British colonies and of Virginia. The Fry-Jefferson map was widely copied, and several French language editions and derivatives were published. It was an important resource for Lewis Evans as he drew A general Map of the Middle British Colonies, in America, and for John Mitchell who created one of the most important political maps of colonial North America, A MAP of the British and French Dominions in North America. Fellow Virginian John Henry relied heavily on Fry and Jefferson’s map as he plotted out Virginia’s county boundaries in his New and Accurate MAP of VIRGINIA, published in 1770. Thomas Jefferson, Peter Jefferson’s son, also used his father’s map heavily while compiling A Map of the country between Albemarle Sounds, and Lake Erie to accompany his Notes on the State of Virginia.
