In November 1846, he was elected on the Democratic and Anti-Rent tickets a canal commissioners.[4] Under the Act of May 6, 1844, there were two canal commissioners to be elected to a four-year term beginning on February 1, 1847, but at the same State election the voters ratified the New York State Constitution of 1846 which extended the terms of the incumbent commissioners until the end of 1847, calling for a new election in November 1847. Thus Hudson could not take office for his elected term. However, shortly before the State election, Commissioner Jonas Earll, Jr. had died, and Hudson was appointed on December 3, 1846, by Governor Silas Wright to fill the vacancy and remained in office until the end of 1847.[5]
On November 18, 1840, Hudson was to married Gertrude Craig (1820–1851), daughter of Archibald Craig, a Schenectady banker,[9] and Anna Maria (née Robinson) Craig.[10][11] Together, they had one son:[1]
Archibald Craig Hudson (1841–1876),[12] who was engaged in the malting business, with Andrew M. Marsh under the firm name Hudson & Marsh, until his death.[13]
Both wife and son predeceased him. At his death, his nearest relatives were his cousin, Sir William Brown of Brown Bros., brokers in New York City, although Sir William lived in London.[14] Hudson died on April 16, 1887, at the Tifft House hotel in Buffalo,[3] his residence for the last twenty years of his life.[14] After a funeral at St. Paul's Cathedral, he was buried at Forest Lawn Cemetery, Buffalo.[15]
