Buck’s family was originally from Ireland, but they settled in Devon in the late seventeenth century and subsequently acquired various properties in the north of the county through marriage and inheritance. His father died when he was seven and his grandfather, George Buck, who died in 1794, had intended that he should take holy orders and be presented with the ‘rectories and advowsons of West Worlington and Bideford’.
He divided against Catholic relief, 6 Mar. 1827, 12 May, and presented two hostile petitions from Exeter, 7 May 1828. He presented a Bideford petition for repeal of the Test Acts, 31 May 1827,
The ministry regarded him as one of the ‘violent Ultras’, and he voted against them in the crucial civil list division, 15 Nov. 1830. He replied to another Exeter requisition by reiterating his general support for tax reductions,
He divided for the second reading of the reintroduced reform bill, 6 July 1831. He presented a petition from the Exeter guardians of the poor for a higher franchise qualification, 12 July, and said he would move for this in committee. He voted with ministers against using the 1831 census to determine the disfranchisement schedules, 19 July, to enfranchise Greenwich, 3 Aug., and Gateshead, 5 Aug., and against giving county votes to urban freeholders, 17 Aug. However, he voted against the disfranchisement of Downton, 21 July, to postpone consideration of Chippenham’s inclusion in schedule B, 27 July, against the partial disfranchisement of Dorchester, 28 July,
In June 1832 Buck intimated that he would not stand at the forthcoming general election and he subsequently issued a valedictory address defending his stance on Catholic emancipation and reform.
