In 1742, it was enacted that Prince William County be divided. The bounds of this county were set as follows: "all that part thereof lying on the south side of Occoquan and Bull Run and from the heads of the main branch of Bull Run by a straight course to the Thoroughfare of the Blue Ridge of Mountains known by the name of Ashby's Gap or Bent." Hamilton was the parish for Prince William County. That portion of Prince William which had, in 1732, been placed in Truro Parish became the new county of Fairfax. The name was, of course, in honor of Lord Fairfax, the Proprietor of the Northern Neck Grant. Pohick, one of the churches in Truro Parish, is still standing and in use. General George Washington, who lived at nearby "Mount Vernon," George Mason of "Gunston Hall" and Lord Fairfax of "Greenway Court" were vestrymen; and planned for the erection of this present building in 1769. In the same year that Fairfax was formed in the northern part of the colony, Hanover County in the middle section was divided. The Act ordered "all that tract of land now deemed to be a part of the said county of Hanover lying above a straight course to be run from the mouth of Little Rockey Creek on the River Northanna south, twenty degrees west until it intersects the line of Goochland County" should become a distinct county and known by the name of Louisa County. The name honored a daughter of George II, as Amelia had done a few years earlier. Two years later the first of the eight counties eventually cut from Goochland was created and given the name Albemarle. This was in honor of William Anne Keppel, second Earl of Albemarle, Governor-General of the Colony, 1737-1754. Like most of the Governors-General, he did not come to Virginia, but the Lieutenant Governor as his deputy, performed the duties of his office. The bounds of Albemarle were to be divided from Goochland on the west "by a line run from the point of fork of James River north, thirty degrees east to the Louisa County line, and from the said point of fork a direct course to Brooks mill and from thence the same course continued to Appomattox River." "The point of fork" is the junction of the Rivanna with the James. It will be noted by the reference to the Appomattox River that Albemarle extended across James River just as Goochland did. "Monticello" the beloved home of Thomas Jefferson, is in Albemarle County, and in architecture and planning is another example of the amazing versatility of his genius.
