Hudson was a Cumbrian of humble origins. His father, a Wigton shopkeeper who is said to have died in 1807 aged 66, has been erroneously identified with the Thomas Hudson who was clerk to the cathedral chapter of Carlisle and still alive many years later. His eldest brother Robert, born in 1764, joined the navy but was killed in action on the Magicienne, 2 Jan. 1783. Another brother, Samuel, died an infant in 1771. His sister Elizabeth married Alexander Donaldson, a Wigton watchmaker, and bore several sons.
At the 1826 general election Hudson stood for Marlborough as part of an abortive bid by the independent association to overthrow the Ailesbury interest. His petition against the return was unsuccessful.
Hudson divided for the second reading of the revised reform bill, 17 Dec. 1831, again steadily supported its details, and voted for the third reading, 22 Mar. 1832. He divided with ministers on the Russian-Dutch loan, 26 Jan., 12, 16, 20 July, and relations with Portugal, 9 Feb. He obtained more returns on trade, 9 Apr., and later that day voted against the recommittal of the Irish registry bill. He divided for the address calling on the king to appoint only ministers who would carry the reform bill unimpaired, 10 May, and paired for the second reading of the Irish bill, 25 May 1832. At that year’s general election he successfully contested Evesham as a Liberal, but he retired at the dissolution of 1834. He died in London in April 1852. By his will, dated 29 June 1850 with a codicil made the day before his death, he provided his wife with a life annuity of £800, in addition to her benefits from their marriage settlement, and devised his real estate in Madeira to his nephew Robert Donaldson. Further annuities were given to the children of his nephew John Donaldson, Anne and Thomas Donaldson, to whom he also transferred a debt of £10,000 owed him by the firm of Henry and John Donaldson (as it was now styled). His Shropshire property, subject to his widow’s life interest, passed to John Donaldson’s second son Charles (1840-93), Conservative Member for Newcastle-under-Lyme, 1880-85, who took the additional name of Hudson in 1862.
