The least distinguished of four brothers, Burnet Abercromby went to sea in the East India Company’s service, and on his visits to Bengal gained the favour of Clive, to whom he appealed for help in July 1767 in getting ‘a good voyage’.
He was returned for Clackmannan through the interest of Henry Dundas, an intimate family friend. On 16 Dec. 1788 and on 11 Feb. 1789 he voted with Administration on the Regency. Dundas wrote to Col. Robert Abercromby in India, 8 Apr. 1789,
Clackmannan was not represented in the 1790 Parliament and Abercromby does not appear to have sought election elsewhere. He died 24 Mar. 1792.
