Buller Elphinstone’s father, the third son of the 10th Lord Elphinstone, entered the service of the East India Company and rose to join the court of directors in 1786, serving as its chairman in 1804, 1806 and 1814. He took the additional name of Fullerton on his marriage to the niece and heiress of John Fullerton of Carberry, whose inheritance in 1802 included the fortified house of Carberry Tower. Through his business acumen he rescued the family fortunes and in 1813 made the symbolic purchase of Elphinstone Tower, Haddingtonshire, the ancestral home.
He was an occasional attender who is not known to have contributed to debate. No trace of activity has been found for the 1827 session. He returned to the half-pay list at his own request in January 1828.
Buller Elphinstone apparently made no attempt to return to the Commons, although he has been identified as a contributor to Conservative funds in Scotland in 1837, 1844 and 1849.
