2. Calm, clear & pleasant as yesterday—Mer. at 60. Mr. Thomson Mason & Lady and Mrs. Nichols dined here.
Thomson Mason (1759–1820), son of Col. George Mason of Gunston Hall, lived at Hollin Hall, just north of GW’s River Farm. The house had been built on land given Thomson by his father. He was a justice of Fairfax County and later served as a state senator (1800–4) and a delegate (1808–9) from Fairfax to the Virginia General Assembly. Mason married in 1784 Sarah McCarty Chichester, daughter of GW’s neighbor Richard Chichester.
