p. 1 1738-1769 - Pulaski County Area a Part of Augusta County:
Augusta County was taken from Orange County in 1738; but due to the unsettled state of the territory the first county court did not convene until 9 December 1745. When the first settlers came into the New River Valley, the territory was a part of the County of Augusta. The boundaries of this huge county were ill defined. Based on the original British claim to the western empire, then being challenged by the French, Augusta County might have been considered as extending from the Blue Ridge Mountains to the Pacific. The county seat of this vast area was Stuanton - and Staunton remains the county seat of present-day Augusta.
1770-1772 - Pulaski County Area a Part of Botetourt County:
The Botetour County Court was organized 13 February 1770. Botetourt, carved out of Augusta County, was also a sizeable county. The western border of the county was the Mississippi River.
