Lawrence Harrison owned the 234½-acre tract at Great Meadows, and in late 1770 GW directed William Crawford to purchase that tract for him. Harrison agreed to sell his rights to the tract to GW for thirty guineas and did so on 4 Dec. 1770. Harrison made the agreement in the name of his son-in-law, William Brooks, to whom Harrison had assigned his right of survey. In October 1771 Brooks confirmed the sale to GW.
