Account books of several generations of the Welch family of Fauquier County, Virginia. The earliest book includes notes, 1767-1778, of Thomas Glascock. The early volumes were probably kept by or for Sylvester Welch (1764-1832), the later ones by or for Sylvester Welch (b. 1800).

The latter Welch seems to have been a merchant and owner of grist mills. One book, 1852-1856, includes ledger accounts with free blacks as well as with slaves. The volume, 1878-1880, concerns a farm. There is a manuscript geometry book, 1854, kept by Sylvester Morgan Welch.
