A dominant figure in Carlisle manufacturing and politics, Ferguson was the second surviving son of Robert Ferguson, a Cumberland linen check manufacturer.
At the 1852 general election Ferguson came forward as a Liberal for Carlisle. In his published address he objected to canvassing, arguing that ‘it may have a tendency to prevent the free and independent exercise of the will of the elector’ and at the nomination he professed ‘his unvarying attachment to the principles of free trade’.
Ferguson dedicated his handful of known speeches to his Carlisle canonries bill. First introduced in March 1854, the bill proposed to suspend the appointment to the next vacant canonry of Carlisle, and appropriate the income to the ‘augmentation of certain ecclesiastical incumbencies’ in the city. According to Ferguson, ‘within the city of Carlisle too much attention altogether had been paid to the higher dignitaries of the Church, while those who occupied the lower stations were almost wholly unprovided for’.
At the 1857 general election Ferguson gave his equivocal support to Palmerston, defending his conduct over events at Canton, but accusing him of being ‘very deficient in the cause of reform: he ought to lead the way instead of being led’.
Ferguson died at Morton House, Carlisle, in February 1863, leaving effects valued at under £35,000.
