Lowther, who claimed that he had ‘a name in which confidence might be placed’, was the eldest son of Colonel Henry Cecil Lowther, MP for Westmorland 1812-1867, and the grandson of William Lowther, first earl of Lonsdale, who in 1802 had inherited the family’s vast estates in Cumberland and Westmorland.
At the 1847 general election Lowther came forward for Cumberland West, where his family owned extensive property, including the port and mining district of Whitehaven. Lowther was unabashed about his family’s political pretensions, insisting that ‘the position and property of his family in the two counties entitled them to use their influence’.
Like his father, Lowther was an occasional attender who made no known speeches. He is also not known to have served on any select committees.
Re-elected unopposed at the 1852 general election, on the hustings he attacked the late Russell ministry for injuring the shipping interest and reiterated that he was ‘an enemy to concessions to the Court of Rome’.
At the 1857 general election Lowther attacked Palmerston’s conduct in foreign policy, but maintaining his unwavering defence of the established church, he reserved the majority of his invective for Maynooth college, describing it as ‘nothing but a hotbed of sedition’.
Re-elected unopposed at the 1865 general election, Lowther poured scorn on the late Liberal government’s foreign policy, accusing Russell of ‘continually bullying small states, and knocking under large ones, and of meddling with things he had better leave alone’.
Lowther successfully defended his seat against Liberal opposition at the 1868 general election, and maintained his staunch opposition to the disestablishment of the Irish church. In March 1872 he succeeded his uncle, William Lowther, as third earl of Lonsdale, inheriting his family’s vast properties in Cumberland and Westmorland. He died, following a period of ‘very indifferent health’, at Whitehaven Castle in August 1876,
