On January 12, 1769, Washington went up to Alexandria to "ye Monthly Ball." He lodged with Captain Dalton and the next day being very bad he was "confined there till afternoon by rain."[78] Sometimes when attending court he "lodged at Captn. Dalton's."[79]

John Dalton's bequest to his daughter, Catherine, included the home place. On April 24, 1793, Catherine and her husband, William Bird, sold to Jonah Thompson and David Findley for £1,500 (about $7,500) the property described as being in Fairfax Street, 60 feet to the north of Cameron, and extending north upon Fairfax Street 119 feet 3 inches to the line of Herbert, Potts and Wilson, thence East parallel to Cameron to cross Water and Union Streets into the Potomac River, thence with a line parallel to Fairfax south 119 feet 3 inches, and included houses, buildings, streets, lanes, alleys, and so on. But the Birds reserved the right to the "use and occupation of the dwelling House now occupied" and the kitchen and garden, until the "1st day of October next" and also reserved unto Lanty Crowe the house "demised unto him to the end of his term, he paying the annual rent thereof unto the said Jonah Thompson and David Findley."[80] Findley died within the year and Jonah Thompson bought from Amelia Findley, the mother and heir of David Findley, equal and undivided portion of the already described lot and paid her the sum of £500 12s.

Jonah Thompson's House purchased from John Dalton's daughter, Catherine Bird

Jonah Thompson was an important citizen of Alexandria. He was a shipping merchant, banker and large property owner. He married Margaret Peyton and they had three sons, Israel, William Edward, and James; a daughter, Mary Ann, married a Mr. Popham, and another daughter, Eugenia, married a Mr. Morgan.

In 1809 Jonah Thompson mortgaged this property to the Bank of Alexandria for $13,500, which he paid within four years. In May 1850, the heirs of Jonah Thompson sold to Benjamin Hallowell for $4,600 a lot beginning at the south side of the alley which divided the block, running south 43 feet 7 inches. Benjamin Hallowell, in turn, sold to James S. Hallowell for nine thousand dollars in April 1854, and from James S. Hallowell and his wife the property passed through various hands until it became St. Mary's Academy.

The Jonah Thompson house, part of it at least already built in 1793, is one of the most interesting houses to be found anywhere. It is unusually large and has two handsome arched stone entrances. One, although similar, obviously was added, as the line of demarcation is plainly visible between the bricks.

The house has been sadly abused with no thought given its architectural merits and much of the woodwork has been removed. The stair is perhaps the finest in Alexandria, with spindles and risers carved in a more elaborate fashion than was the practice of the thrifty Scotsmen of Alexandria. At the rear of this large house, separated only by a narrow area, stands another house, facing the long garden and originally the river. The front of this house boasts the loveliest bit of Georgian architecture left in the old seaport. A pure Adam loggia, executed in stone, runs across the garden façade. While arches are now filled in and clothes hung to dry flap on the gallery, the outline is so chaste in its classic form that nothing can destroy the illusion of beauty.
