The first Settlers of Augusta County, Virginia arrived in the 1720's primarily from Pennsylvania, Maryland and Eastern Virginia. Some were German-born or the Pennsylvania-born children of German-speaking Protestant immigrants from the Palatinate and other areas bordering the Rhine River. These were Lutheran, Reformed, or Brethren. The greatest numbers of early Augusta settlers were from the province of Ulster in the north of Ireland, or were the Pennsylvania and Maryland-born children of these Ulster Scots or Scotch-Irish Presbyterians. Many early settlers took up land on the 112,000-acre tract that the colonial government granted to William Beverley, later referred to as "Beverley Manor".
In 1739, Benjamin Borden a New Jersey Quaker, received a grant beginning at the southern boundary of Beverley Manor. Borden was promised 1,000 acres for every settler he located, amounting in all to 92,100 acres. John McDowell, a surveyor, helped Borden locate his tract and was rewarded with a large acreage. The "Borden Tract" later became Rockbridge County, VA. In addition to the Scot's Irish, English and African-Americans were also among the early settlers in the area. Many settlers were of of English descent, coming into the area from eastern Virginia. African Americans were also among the early settlers, some free-born, but most enslaved. Although initially small in number, by the Civil War they represented 20% of the population. (Source: Augusta County Historical Society, http://www.augustacountyhs.org/history.html)
Augusta County was created from Orange County in 1738. For seven years, until the population grew large enough, Augusta’s records were kept in Orange. In 1745, Augusta elected a sheriff, a vestry, a county court, a minister, and a clerk of court. A courthouse was built on the same site in Staunton (originally called Beverley’s Mill Place) as the current courthouse. The county’s records have been kept continuously at the courthouse since 1745. In that year, the county included all of present southwestern Virginia, most of present West Virginia and even stretched to the Mississippi River. As people began to settle in those western areas, new counties were formed from parts of Augusta, beginning in 1769 with Botetourt County, then Rockingham and Rockbridge in 1778.

Settlers of the James River
Settlers of the Upper Potomac (Included three major watershed: The Cacapon River (a portion of which was known as the "Lost River of Calaphon"), The South Branch of the Potomac, and the North Branch of the Potomac)
Augusta County was established in 1738 from part of Orange County (which was formed from 1734 from part of Spotsylvania). Initially, it covered a very wide area extending south to the modern Tennessee Border, and westward into Kentucky what is now West Virginia, and beyond. 0ver the next 150 years Augusta was repeatedly subdivided into more manageable units, until it finally reached its present size and configuration. As the county evolved, settlers once in "Old Augusta" found themselves in the new daughter counties. In some cases, this happened because they physically moved to new locations within the boundaries of Old Augusta, and in other cases, they never left their original homesite, with the area in which they lived successively being redesignated as part of a series of successive daughter counties.
A consequence of this is that in order to keep track of early settlers that lived in the Augusta County, Virginia area, one must take into account the areas within and adjacent to Augusta County's original boundaries that later formed other Virginia Counties (up to 1799). The following is intended to help keep track of these changes. Eventually, the plan is to include maps showing the repeated subdivision of the area once known as "Augusta County".
