GW may have originally planned to combine this visit to Eltham and Williamsburg with attendance at a session of the House of Burgesses which, although scheduled to open on 1 May, had met from 31 Mar. to 16 April (JHB description begins H. R. McIlwaine and John Pendleton Kennedy, eds. Journals of the House of Burgesses of Virginia. 13 vols. Richmond, 1905–15. description ends , 1766–69, 138, 140, 175–77). Billy is William Bassett (1760–1774), eldest son of Mrs. Washington’s sister Anna Maria Dandridge Bassett and Col. Burwell Bassett of Eltham. The Washingtons probably stayed at the home of Thomas Lawson, who ran John Tayloe’s ironworks on Neabsco Creek, Prince William County, from which GW bought some bar iron in 1761 (ViHi: Tayloe Papers; Lawson to GW, 28 June 1761, ICHi).
