Maitland’s father and uncle Alexander, grandsons of a presbyterian minister in the west of Scotland and nephews of another, were London merchants trading from 13 King’s Arms Yard. They and Maitland’s three elder brothers (Robert, Henry and Ebenezer) were buried in Bunhill Fields, but it would appear that he conformed to the established church. His uncle Alexander’s heiress married Sir John Sinclair; and he was the uncle of Ebenezer Fuller Maitland.
Maitland did not return himself in 1812 and had made little mark in the House. He is not known to have contributed to debate, though in 1803 he gave evidence to the committee on woollen manufactures in conflict with that of his Chippenham rival Charles Brooke in that he favoured the introduction of machinery. He was at first listed a supporter of Pitt in September 1804, but his name was scored through without being transferred; in July 1805 he was definitely listed favourable to Pitt. He was a defaulter, 2 Mar. 1807, and considered ‘friendly’ to the abolition of the slave trade. Was it he or his nephew Ebenezer who as ‘G. Maitland’ voted against the convention of Cintra, 21 Feb. 1809? In 1810 he rallied to Perceval’s ministry on the address, 23 Jan., and on the Scheldt inquiry, 26 Jan.; was absent on 23 Feb.; joined the opposition majority on 5 Mar., but sided with ministers on 30 Mar. The Whigs listed him ‘Government’. He was also a ministerial voter on the Regency, 1 Jan. 1811, and on Stuart Wortley’s motion, 21 May 1812.
In 1817 Maitland again returned himself for Chippenham when Robert Peel found another seat. He voted with ministers on their use of informers against radicalism, 5 Mar. 1818, and in favour of the Duke of Clarence’s marriage grant, 15 Apr. He still wished to dispose of his interest, and retired on a plea of ill health at the dissolution; but his nominee was defeated at the ensuing election and in an address of 30 July he complained bitterly of the treachery of his agent there.
Maitland bought Woodford Hall about 1801 and in 1825 succeeded to Loughton Hall and manor under the will of Miss Ann Whitaker.
