Prince William County is a county located on the Potomac River in the Commonwealth of Virginia in the United States, and is part of the Washington Metropolitan Area. As of the 2010 United States Census, Prince William County had a population of 402,002. Its county seat is the independent city of Manassas. It is part of Northern Virginia and is one of the highest-income counties in the United States.
See Wikipedia for a history of the county.
Prior to the colonists patenting land beginning in the 1650s, the area was populated by the Doeg tribe.
Although the first patent of land in Prince William dates from 1653, few settlers chose to settle in the area of the county until the early 1700s, because the region was the scene of the bloodiest fighting and slaughters in the Indian wars which continued throughout the seventeenth century.
Along the branches of Quantico Creek and the north branches of Chopawamsic, the following men took up patents between 1694 and 1743: William Bennett, Samuel Jackson, Abraham Farrow, Thomas Harrison, Robert Headges, William Halley, Henry Lucas, Henry Halley, Francis Jackson, Wansford Arrington, Philemon Waters, John Ashmore, John Farrow, John McMillan, William Spiller, Charles Green, and Bertrand Ewell. (From Prince William A Story of its People and Places, WPA, 1941, Pg 27)
The county was formally created in 1731, named for Prince William, Duke of Cumberland and son of King George II of Great Britain. Its initial population centered around Manassus (a railroad junction) and Occoquan and Woodbridge along the Potomac River.
At the time of the county's 1731 inception, Prince William included all or part of the following counties: Prince William, Fairfax, Fauquier, Loudoun, and Arlington. Fairfax County was cut off in 1742, and Loudoun in 1757. With the establishment of Fauquier in 1759, Prince William achieved its present boundaries.
"HISTORIC MARKERS IN VIRGINIA"
Many of Prince William's records were destroyed in both the Revolutionary and Civil Wars, and some deed and bond books were stolen by Federal occupation troops. These were later returned, but the early marriage records have been lost and are presumed destroyed. Most of the surviving original records are now housed in the Library of Virginia or the College of William and Mary Library in Williamsburg.
