GW today advanced his mother £4 12s. 6d. on the money that he was to pay her under their agreement (Mary Washington’s account with GW, 14 Sept. 1771–30 Mar. 1775, PHi: Gratz Collection). The exact amount he owed her was not set until 15 Oct., when Fielding Lewis and Charles Washington finished evaluating her property. GW, they determined, was to pay £93 11s. 8d. for her livestock, £30 a year rent for the Little Falls Quarter, and £92 for a year’s hire of her slaves: six men and four women, half of whom were at Ferry Farm and half at Little Falls (“Sundrys belonging to Mrs. Mary Washington valued by Chas. Washington & Fielding Lewis,” 15 Oct. 1771, ViMtvL).
