Campbell’s grandfather Walter Campbell, an advocate, succeeded his brother Daniel as heir of entail in 1777. He subsequently sold his Lanarkshire property at Shawfield and left the Argyllshire island of Islay and the Lanarkshire estate of Woodhall to his eldest son (with his first wife Eleanor Ker) John Campbell, a captain in the Scots Guards. In 1796 John Campbell married his kinswoman Lady Charlotte Campbell, younger daughter of the 5th duke of Argyll, the colonel of his regiment. He left the army, took up residence in Buckinghamshire and in 1807 was returned for Ayr Burghs on the interest of his Whig brother-in-law the 6th duke, whose political line he followed in the House. He predeceased his father in March 1809, leaving his widow ‘in uneasy circumstances’ with eight young children. The following year Lady Charlotte became a lady-in-waiting to Caroline, princess of Wales, in whose service she remained until 1815. In 1818 she married, against her brother’s wishes, the Rev. Edward Bury, rector of Lichfield, who had been tutor to her elder son Walter Frederick during travels in Italy after leaving Eton. A woman of beauty and charm, with literary pretensions, who had mixed in Sir Walter Scott’s circle, she published from 1822 a series of sentimental novels. Her Diary, which covered her time in the princess’s household, sold well, despite a critical mauling, when it was published anonymously in 1838. Her second husband died in 1832, but she survived until 1861.
Walter Frederick Campbell succeeded his grandfather in 1816 and came of age three years later. In 1822 he replaced his uncle Lord John Campbell, Argyll’s brother, as Member for Argyllshire. Lord John would have preferred their kinsman Duncan Campbell of Lochnell, Member for Ayr Burghs, 1809-18, but the duke was persuaded by others to ‘support only a Whig’.
At the general election in July 1826 he comfortably defeated Lochnell.
At the general election that summer he voted for the unsuccessful Whig in Lanarkshire and was himself returned unopposed for Argyllshire.
Campbell, whose first wife died in September 1832, did not stand for Argyllshire at the general election in December, but he was returned unopposed in 1835, defeated a Conservative in 1837 and retired from Parliament in 1841. On 22 Sept. 1847 he made a will leaving all his property to his elder son John Francis (1822-84), confirming the terms of his second marriage settlement and directing that his five-year-old younger son Walter should be trained as a merchant and be sent abroad for this purpose, in order to remove him from ‘the temptations of home’.
