[1] He succeeded in 1808 to estates at Firbeck and Langold Park which his father had inherited in 1804 from his brother John Gally Knight.

[3] He was a Member of Parliament for the constituencies Aldborough (12 August 1814 - April 1815), Malton (1831–1832; 31 March 1835 - 9 February 1846),[2] North Nottinghamshire (1835 and in 1837).

[3] Knight was the subject of the 1818 satirical poem "Ballad to the Tune of Salley in our Alley" by Lord Byron, in which Byron facetiously accuses him of being not only a poetaster, but a dandy as well.

[11] He rode upon a Camel's hump ⁠Through Araby the sandy, Which surely must have hurt the rump ⁠Of this poetic dandy.

His rhymes are of the costive kind, ⁠And barren as each valley In deserts which he left behind ⁠Has been the Muse of Gally.
