Fetherston, who was described by a local Tory in 1830 as a ‘very proper man’, continued to sit for county Longford on the interest of the dowager Lady Rosse, by whom he had been returned in 1819 as his father’s successor with the backing of the other Member, Lord Forbes.
At the 1826 general election he offered again, the Catholic press describing him as ‘an Orangeman, though not perhaps of the extreme hue’, and was returned unopposed.
At the 1830 general election he offered again, but Lady Rosse having put up a second candidate, shortly before the nomination he withdrew from the probable contest, boasting that ‘in the worst of times I never courted popularity by a desertion of those principles which I conscientiously entertained, nor did I ever hesitate to oppose any measure which I thought injurious to the interests of my country’.
