Smyth was descended from a family of London drapers and silk merchants. Robert Smyth (c. 1594-1669), who was knighted in 1660 and created a baronet in 1665, bought the Upton estate at West Ham. The 4th baronet, Sir Trafford Smyth (c. 1720-66), inherited from his uncle James Smyth (d. 1741) the Berechurch property near Colchester.
George Smyth, who came into full possession of the Berechurch estate in 1805, took a quite different approach to life and politics. He settled at Berechurch, extended the estate and rebuilt the house, made himself respected and popular in Colchester and established himself as one of the leading figures in the anti-Catholic Tory Blue party, which dominated municipal politics through the corporation.
Smyth presented petitions against Catholic relief from the archdeaconry and inhabitants of Colchester, 2 Mar., and the corporation, 5 Mar. 1827.
At the Pitt Club meeting in November 1828 Smyth urged the formation of a local Brunswick Club; he duly became its first president, 8 Dec. At the mayoral election, 30 Nov. 1828, he ‘avowed himself a staunch supporter of the Protestant cause’, suggested that ministers looked ‘favourably’ on the Brunswickers and ‘attributed the present quiet attitude of the Irish agitators to the soldiers that had been sent to Ireland by the duke of Wellington’.
Smyth remained prominent in Colchester politics. At a meeting called to petition for repeal of the beer and malt taxes, 19 Dec. 1829, he admitted to being ‘wholly ignorant’ on the currency question, hoped that the ministry would alleviate the tax burden and discounted the radical nostrum of a property tax. He did this again at the Essex county meeting, 11 Feb. 1830, when he demanded economy and retrenchment.
