Born in co. Dublin, Stock was one of fifteen siblings and half-siblings from the two marriages of his father, whose first wife (Stock’s mother) was the sister of William Newcome (1729-1800), Protestant archbishop of Armagh.
A graduate of Trinity College, Dublin, Stock became a doctor of civil law in 1815, took silk in 1835, and was appointed a serjeant-at-law in 1840. A staunch Whig, he attended a meeting at the Coburg Gardens, Dublin to express public confidence in the Irish administration, 15 May 1837. As a Liberal candidate, he finished a poor third behind two Conservatives in the contest for Dublin University, 4 Aug. 1837, and was outspoken in his criticism of the Conservatives’ petition against the return of Daniel O’Connell and Robert Hutton for the city.
Stock was warm in his praise for the Whig ministry, particularly the contributions made by Lord John Russell and Lord Morpeth.
Stock was an advocate of the benefits to Ireland of the development of steam navigation between Europe and America and was a member of the deputation on communication links between Ireland and England that waited on the prime minister, Sir Robert Peel, 25 June 1842.
Though Stock appeared sympathetic to ‘the spirit of democracy’ which had arisen in England during the Chartist agitation, he was absent from the division on Sharman Crawford’s motion on parliamentary reform, 21 Apr. 1842.
Stock regretfully announced his resignation after dissenting with his constituents over the paramountcy of the repeal question in November 1845 and took the Chiltern Hundreds, 22 Jan. 1846.
Stock performed the duties as a judge of assize on the Munster circuit from 1846, where he was remembered as ‘patient and laborious’ though ‘not very capable’, and resigned his serjeancy, for reasons unknown, in June 1851.
