Copeland’s grandfather William Copeland (1728-76) had connections with Astbury, near Congleton, Cheshire, but farmed in the Potteries area of Staffordshire at Hollybush, Longton Hall, Stoke. With his wife Ann, daughter of Thomas Eaton of nearby Audley, he had a son and namesake, born in 1765. William Copeland the younger was probably apprenticed to the Stoke pottery manufacturer Josiah Spode, who made his family’s fortune with his successful range of transfer printed ‘blue ware’. He subsequently went to London to assist Spode’s son Josiah junior in the management of the firm’s warehouse and retail outlet, which was located originally in Fore Street and, from about 1794, in large premises (the site of a former theatre) at 5 Portugal Street, Lincoln’s Inn Fields.
William Taylor Copeland, his only son, was presumably trained for the business, in which he took a quarter share by his father’s gift, 1 Jan. 1824, when its London stock value was £28,000.
A member of the Irish Society, which managed the City’s estates in county Londonderry, at the general election that spring Copeland was put up for Coleraine by the independent interest opposed to the dominance of the corporation and the Beresford family. Portrayed as a reformer, although he never joined Brooks’s, he had a substantial lead after the poll, but his opponent was returned by virtue of having a majority of corporators’ votes. The petition lodged in his name, claiming a majority of legal votes among the freemen, 1 July, proved successful, and he was seated, 4 Aug. 1831.
Copeland voted for the second reading of the revised reform bill, 17 Dec. 1831, to go into committee on it, 20 Jan., and for the disfranchisement of 30 boroughs in schedule B, 23 Jan., and the £10 householder franchise, 3 Feb. 1832. Although he divided against ministers on the cases of Helston, 23 Feb., and Gateshead, 5 Mar., he sided with them for the third reading, 22 Mar. He voted against Hobhouse’s vestry reform bill, 23 Jan., when he successfully moved for information on freemen admissions and corporation properties in Coleraine. In reply to criticism from the Member he had unseated, he stated that he had been urged to introduce the motion ‘by a vast number of inhabitants’, but admitted that he had ‘never set foot upon Irish ground’. He divided with opposition against the Russian-Dutch loan, 26 Jan., but with government against the production of information on Portugal, 9 Feb. He voted in minorities for inquiry into distress into the glove trade, 31 Jan., 3 Apr., and the Sunderland (South Side) Wet Docks bill, 2 Apr. He presented the London corporation’s petition endorsing the orders in council on slavery, 4 Apr., but dissociated himself from it because he considered that the orders posed a threat to British shipping and were not in any case ‘calculated to ameliorate the condition of the slaves’. He left the House without voting on Ebrington’s motion for an address calling on the king to appoint only ministers who would carry the reform bill unimpaired, 10 May. He voted for the second reading of the Irish reform bill, 25 May, but for Frederick Shaw’s amendment to preserve the voting rights of Irish freemen, 2 July, when, citing the Coleraine case, he called for ‘hereditary’ freemen to be disfranchised. His only other vote that session was for making coroners’ inquests public, 20 June 1832.
At the general election of 1832, when he supported the beaten Conservative candidate for London, Copeland, who had again canvassed as a reformer and the champion of the independent interest, was defeated at Coleraine by the casting vote of the mayor, but his subsequent petition was again successful.
