No search of records reveals how or why these two houses stand back to back. Whether Jonah Thompson built the first for his bank or business offices, or whether his family outgrew the house and he needed more room is not known. The two are treated as one house in all the documentary evidence, and one's curiosity, interest, and imagination are excited by the twin or married houses. One story has it that Jonah Thompson built the rear or twin house for his eldest son so that the two families might be together but with separate ménages.

Captain John Dalton forged a link between Mount Vernon, his family, and his posterity that was stronger than he knew. It was his granddaughter who was so deeply distressed at the ruin and desolation of the home of Washington that she fired her daughter's imagination with an idea that saved the spot for the nation. This great-granddaughter of John Dalton was Ann Pamela Cunningham, whose name will ever be indissolubly connected with Mount Vernon. In 1853 she formed the Mount Vernon Ladies' Association, and as its first regent stirred the women of America with her ardor and directed the entire campaign until adequate funds were collected. In 1859 John Augustine Washington sold the Mount Vernon estate to Miss Cunningham for two hundred thousand dollars—after the Virginia Legislature and the federal government had both refused to acquire it.
This sale was negotiated by the Alexandria banker, John W. Burke, who was appointed executor and guardian of John Augustine Washington's estate after he was killed during the Civil War while on active duty as a member of General Robert E. Lee's staff.
When the war broke out, Alexandria was occupied by Union troops. The Union authorities knew of the sale of Mount Vernon and repeated but futile efforts were made to find the securities. Mr. Burke's home was searched no less than three times. The funds were never found in their hiding place of the soiled-clothes basket. There they reposed until Mrs. Burke (née Trist, great-granddaughter of Thomas Jefferson) and Mrs. Upton Herbert (née Tracy), both Philadelphia-born ladies, sewed the bonds in their petticoats and with high heads carried them through the Union lines to Washington and delivered them to George W. Riggs, who held them for the duration of the war, when he returned them to Alexandria—and Mr. Burke.
An interesting sequel to the story occurred only a short time ago when the last of John Augustine Washington's children died. Mr. Taylor Burke, grandson of John W. Burke, and president of the Burke & Herbert Bank, administered the estate of the late Mrs. Eleanor Washington Howard, and distributed her estate, composed of the remainder of that purchase price, among her heirs.[81]
