as unconstitutional, bordering on treasonous. The Treaty of Ghent, signed while the convention was meeting, effectively ended both the Federalist Party and Cabot's political career. He made no further public appearances and no longer maintained his correspondence with public figures, save a brief discussion with Pickering weighing the merits of free trade. Retirement After the Hartford Convention, Cabot returned to a life largely of leisure. He remained president of the Boston Marine Insurance Company, which kept him in touch with his merchant colleagues. He was an active member of Boston society and devoted much of his time to his wife, daughter Elizabeth, and son Henry who lived nearby with his family. Personal life Cabot steadfastly refused to have his portrait painted during his lifetime; most depictions of him are posthumous. He was described by contemporaries as tall and "powerfully built." Samuel Griswold Goodrich, a witness to the Hartford Convention, described him as bearing a striking resemblance to George Washington. Cabot was raised as a member of the Congregational Church of New England but later in life became a Unitarian. He was averse to public speaking but considered an excellent conversationalist in private. Among his close friends was Josiah Quincy II, who later became President of Harvard University. Historian George Bancroft credited Cabot with encouraging him to study abroad at the University of Göttingen, where he was among the first Americans awarded a Ph.D. He was elected a fellow of the American Academy of Arts and Sciences in 1788. Family Cabot married his second cousin Elizabeth Higginson in 1774.

Henry and Elizabeth lived into adulthood. Elizabeth married John Thornton Kirkland, the fifteenth President of Harvard University. Through Henry's daughter Anna, George Cabot was the great-grandfather of Henry Cabot Lodge, who held Cabot's seat in the United States Senate from 1893 until his death in 1924. Lodge's grandson Henry Cabot Lodge Jr. also represented Massachusetts in the Senate from 1937 to 1943 and again from 1947 to 1953. In 1795, Cabot was briefly the guardian of Georges Washington de La Fayette, son of the Marquis de Lafayette, who
