Virginia. Augusta County. Chancery Court Case No. 1834-01, Borden v. Borden, "Deposition of Joseph Walker," 17 August 1807; digital images, The Library of Virginia, Chancery Records Index, Virginia Memory (http://www.virginiamemory.com/collections/chancery/: accessed 24 December 2014), images961-963. Joseph testified his age was 63 years and eight days on 17 August 1807 placing his birth on 9 August 1744. It is unclear if the testimony he gave takes into account the change from the Julian to the Gregorian Calendar in 1752.
