This monumental work consists of court records pertaining to the Scotch-Irish pioneers who first breached the mountain barrier sealing off the Atlantic seaboard from the country west of the Blue Ridge. In 1745, when Augusta County, Virginia was erected, its domain extended from the Alleghenies to the Mississippi River, and from the northern part of Tennessee to the Great Lakes. So, this stands as the supreme source of genealogical information for hundreds of thousands who trace their ancestry to Augusta County, and the Great Valley of Virginia.

The first volume has abstracts of court order books (1745-1799), plus notes from county court judgments, original papers on suits (1745-1825), and petitions filed in court from 1745 on. Volume II has records of the circuit and district courts, marriage bonds, licenses and returns (1748-1800), land entries (1744-1751), guardians' bonds (1782-1801), administrators' bonds (1776-1810), tax delinquents (1748-1804), proceedings of the Vestry of Augusta Parish (1746-1799), and records of military service in colonial wars and the Revolution. Volume III has will abstracts (1745-1818) and deed abstracts (1745-1792). Each volume is indexed, and the combined total of names is over 50,000!
