Antrobus came from an old Cheshire family based at Congleton. His father, who was said to have spent a short period of time at the stock exchange, before becoming a partner (with his elder brother Edmund) of the London banker Thomas Coutts in 1784, suffered a riding accident in 1793 and spent the final months of his life in a coma, unaware that his wife had died after giving birth to their second son.
Having returned to England, Antrobus’s first recorded vote was with Lord Liverpool’s ministry against abolition of one of the joint-postmasterships, 13 Mar. 1822; he gave general support to them thereafter. He divided against relieving Catholic peers of their disabilities, 30 Apr. In his only known intervention in debate, on the civil list, 15 May, it was reported that ‘not a word of what he said was audible in the gallery’.
The ministry regarded him as one of their ‘friends’, and he duly voted with them in the crucial division on the civil list, 15 Nov. 1830. He divided against the second reading of the Grey ministry’s reform bill, 22 Mar., and for Gascoyne’s wrecking amendment, 19 Apr. 1831. He came in again for Plympton Erle at the ensuing general election. He divided against the second reading of the reintroduced reform bill, 6 July 1831. He voted for use of the 1831 census in determining the disfranchisement schedules, 19 July, and against the partial disfranchisement of Chippenham, 27 July, and the bill’s passage, 21 Sept. He divided against the second reading of the revised bill, 17 Dec. 1831, the enfranchisement of Tower Hamlets, 28 Feb., and the third reading, 22 Mar. 1832. He voted against ministers on the Russian-Dutch loan, 26 Jan., 12 July, but with them against Hunt’s motion on military punishments, 16 Feb. 1832.
The disfranchisement of Plympton Erle by the Reform Act ended Antrobus’s parliamentary career, and he concentrated on developing his Cheshire estates. He died in May 1861 and Eaton Hall passed to his only son from his first marriage, John Coutts Antrobus (1829-1916).
