Lord Catherlough had no surviving legitimate sons by his two marriages but, not long after the second, commenced a liaison with Jane Davies, sent, so the story went, by her father to placate him when the rent was overdue, which produced four children. Robert, the eldest, inherited the Knight estates, his mother taking that surname by Catherlough’s will.
Knight joined Brooks’s Club, 1 Feb., and the Whig Club on 3 Apr. 1792. In January of the same year he had unsuccessfully contested the Warwick by-election as an independent against the Earl of Warwick’s nominee. He was one of the Friends of the People. On 18 May 1797 he was a steward of the Crown and Anchor meeting for parliamentary reform, chaired by Sir Francis Burdett, supported household suffrage at the Marylebone meeting, 30 May, and in the same month, as sheriff of Warwickshire, sent in an anti-ministerial petition.
Knight was expected to find another seat on the open market, but he did not find one and continued to cultivate Wootton Bassett.
Knight did not go to the poll in 1812 when faced with another contest at Wootton Bassett. John Cam Hobhouse, describing him as a friend of Sir Francis Burdett, quoted him as saying in February 1814 that if the allies reached Paris, he would go to America: he was a Buonapartist, and Hobhouse reported ‘little Knight’ as rejoicing at the Emperor’s return to France in 1815. In 1818 Hobhouse and Knight were proposed to the electors of Milborne Port by an irresponsible local agent, as well-to-do friends of Romilly and Brougham: the manoeuvre was quashed by Hobhouse, 16 June.
Knight was awarded £7,000 damages in 1805 for his wife’s crim. con. with Col. Fuller. He subsequently repudiated his son and heir and neglected his estate, as if to avenge his illegitimacy.
