Dawkins’s ancestors were among the first English settlers in Jamaica: his grandfather Henry Dawkins (1728-1814), who owned 20,000 acres there, bought estates in Oxfordshire and Wiltshire and became a Member of Parliament in 1760. His father, who inherited the Oxfordshire property, sat for Boroughbridge and later Aldborough on the interest of his wife’s cousin the 4th duke of Newcastle, who in 1810 obtained for him the post of commissioner of crown lands, which he held for 22 years. Dawkins was an army officer who served in the Peninsula from January 1810, acting as a major of brigade from June of that year. He was severely wounded at the blockade of Bayonne, but he recovered sufficiently to fight at Waterloo. He subsequently remained in France with the army of occupation.
He was a fairly regular attender who gave general support to Lord Liverpool’s ministry. He voted in defence of their conduct towards Queen Caroline, 6 Feb. 1821. He divided against Catholic relief, 28 Feb. He voted against repeal of the additional malt duty, 3 Apr., reduction of the grant for the adjutant-general’s office, 11 Apr., and repeal of the agricultural horse tax, 14 June.
He divided against Catholic relief, 6 Mar., and the spring guns bill, 23 Mar. 1827. He presented a Boroughbridge petition against repeal of the Test Acts, 19 Feb., and voted accordingly, 26 Feb. 1828. He divided against Catholic relief, 12 May 1828. In February 1829 Planta, the Wellington ministry’s patronage secretary, listed him among those who were ‘opposed to the principle’ of Catholic emancipation, and he duly voted against the government’s measure, 6, 18, 23, 30 Mar., as the diehard Newcastle expected him to. However, his name does not appear on the lists compiled that autumn by the Ultra leader Sir Richard Vyvyan*. He divided for Knatchbull’s amendment to the address on distress, 4 Feb., but voted with ministers against the transfer of East Retford’s seats to Birmingham, 11 Feb., and the enfranchisement of Birmingham, Leeds and Manchester, 23 Feb. 1830. He defended the role of the military college, from which he had personally ‘derived great advantages’, 26 Feb., and did not think it could ‘with propriety be done away with’. His last recorded vote was against abolition of the death penalty for forgery, 7 June 1830. He retired at the dissolution that summer, on account of ‘ill health’.
In 1852 Dawkins inherited his father’s estate at Over Norton. He died there in November 1864 and the property passed to his eldest son, William Gregory Dawkins (1825-1914), an officer in the Guards.
