Peter Jefferson

Peter Field Jefferson (February 29, 1708 – August 17, 1757) was a planter, cartographer and politician in colonial Virginia best known for being the father of the third president of the United States, Thomas Jefferson. The "Fry-Jefferson Map", created by Peter in collaboration with Joshua Fry in 1757, accurately charted the Allegheny Mountains for the first time and showed the route of "The Great Road from the Yadkin River through Virginia to Philadelphia distant 455 Miles"—what would later come to be known as the Great Wagon Road.
