Lowther, who bore a strong physical resemblance to his brother and close confidant the 1st earl of Lonsdale, had been confirmed in possession of Swillington and Yorkshire estates worth £4,000 a year on the death in 1802 of their cousin Lord Lonsdale. Subsequently his interests focused increasingly on that county and the rebuilding of his castle at Wilton, near Middlesbrough, to the design of Smirke. Despite his growing disenchantment with parliamentary life, he remained one of the Lowther ‘ninepins’ for over 50 years, voting steadily with successive Tory ministries and against parliamentary reform and Catholic relief.
Lowther was briefed personally on policy by Lonsdale as hitherto, but his votes were now directed by his nephew Lord Lowther*, whom he had advised to play a more prominent part in organizing the family Members.
Lowther, who received a month’s leave on urgent business, 16 Mar. 1827, remained one of his brother’s closest political confidants in the 1826 Parliament.
Out of Parliament Lowther retained a keen interest in Yorkshire politics and John Henry’s career as Member for York, and he encouraged his son Charles Hugh, who was blind from infancy, to establish a library of embossed books for the blind. He died at Swillington in May 1844, eight days before his wife.
