His brother, Doctor Thomas Smith, was the owner of the "treason house" in West Haverstraw, Rockland County, New York that was being occupied by his other brother, Joshua Hett Smith, at the time that Benedict Arnold and Major John André planned their conspiracies.
Career
During the American Revolution, he was referred to as "the weathercock" because his contemporaries were not able to understand which side he was on. Basically, though, he was neither friend to American nor Loyalist and was one of the main reasons that the loyalists themselves declared that they did never trust the family of Smith. In 1752, along with William Livingston and John Morin Scott he founded a weekly journal, the Independent Reflector. He and his brother Joshua Hett Smith escaped prosecution and probable execution by the Commission for Detecting and Defeating Conspiracies in the State of New York in 1778 for the crime of treason due to the memory of their father's influence upon the Justice system: the elder William Smith had, despite the efforts of friends and relatives, refused appointment to the Office of Chief Justice of the Province of New York in 1760, which his son William then accepted. In 1776, he moved to Albany to avoid the contentious politics but in 1778 declared his allegiance for the loyalist cause and joined the British in New York City. Smith was escorted across the lines by Aaron Burr and became an important adviser and confidant of the military and civilian officials including both Governor William Tryon and General Sir Henry Clinton. In 1780, he was appointed Chief Judge of New York but by this time the office only related to the small part of the Province that was still in British hands. The real judicial power was held by Daniel Horsmanden. He published the first history of New York, The History of the Province of New-York, from the First Discovery to the Year M.DCC.XXXIII. To which is annexed, A Description of the Country, with a short Account of the Inhabitants, their Trade, Religious and Political State, and the Constitution of the Courts of Justice in the Colony. in 1757. Smith returned to England in 1783 and then came to Quebec City in 1786, when he was named Chief Justice for the province and also named to the legislative council. In 1791, he became chief justice for Lower Canada and was appointed to the Legislative Council of Lower Canada, serving as its first speaker.
Personal life
He married Janet Livingston, of the Livingston family of New York. In 1770, he built a manor house in West Haverstraw, New York. From July 15 to July 18, 1778, while his sister Martha and her husband Col. Ann Hawkes Hay were living in the house, it served as headquarters for General George Washington. The house burned down and the Fraser-Hoyer House later built on the site. He died in Quebec City in 1793. He was buried at Mount Hermon Cemetery in Sillery. Smith's diary and selected papers were compiled and edited in two volumes by L.F.S. Upton in 1963 as part of the Champlain Society's General Series.
