Humphrey Knight was overseer of GW's farms at Mount Vernon in 1757 and 1758 until his death in the fall of 1758. When closing out his account with the deceased Knight, GW wrote: “Note, this Humphrey Knight was an Overseer of mine & died while his Second Crop was growing—his share of which it is supposd coud not amount to so much as the Balle of the Acct for which he is here credited—viz.—for 30.15.9½” against a total indebtedness of £69.13.1½ incurred from 20 June 1757 (Ledger A, 73).
