Input: Question: What is the population of the city founded by William Byrd II? Passage:Coal mining in the Midlothian area of Chesterfield County began in the 18th century. Around 1701, French Huguenot settlers to the area discovered the existence of the coalfield. The coalfield was part of the Richmond Basin which is one of the Eastern North America Rift Basins which contains some sedimentary rock and bituminous coal. In a 1709 diary entry William Byrd II, who is credited as the founder of Richmond, and had purchased of land in the area where coal was found, noted that "the coaler found the coal mine very good and sufficient to furnish several generations." It was first commercially mined in the 1730s, and was used to make cannon at Westham (near the present Huguenot Memorial Bridge) during the American Revolutionary War.
