A former army officer with East Indian connections, Graham had had to wait until the death in 1819 of his uncle Thomas Graham of Kinross to come in for that county, and sat only briefly as an unobtrusive supporter of Lord Liverpool’s administration and their Scottish manager Lord Melville before the representation transferred to Clackmannanshire at the dissolution in 1820.
The death on 5 Feb. 1827 of his wife’s uncle, the Rev. William Foster Pigott of Eton College, a wealthy pluralist and royal chaplain, invoked a settlement of 23 Aug. 1815 giving Graham and his wife joint possession of the Cambridgeshire estate of Abington Pigotts, held since before 1500 by the family of Foster Pigott’s late wife Mary (d.1815). Graham accordingly assumed the names Foster and Pigott, 12 Mar., executed Foster Piggott’s will (dated 20 Mar. 1820 and sworn under £25,000) and settled with his family in Cambridgeshire, where he authorized timber sales and improvements at Abington Hall and became an active magistrate and promoter of the Society for the Propagation of the Gospels.
