Thomas Mott, the son of William and Susan Mott, was baptised at All Saints' church, Cambridge, on 6 December 1773. On 18 January 1796 he married, at St Edmund's church, Cambridge, a daughter of Edward Gillam, merchant and carrier (Stamford Mercury, 22 Jan. 1796, p. 3). He was buried at Cambridge 2 July 1826 (ancestry.co.uk).
He was an early friend of Dawson Turner, with whom he made a tour of Derbyshire in 1795. After serving as a clerk to Joseph Sayers at Yarmouth, he became an attorney at Cambridge, where, according to Turner, 'he brought a sad career to a premature end'. Turner described him as ‘a man of quick talents, with considerable taste for poetry, and still more for drawing caricatures’.
In 1817 he published at London a small work entitled Elucidation of the Ancient English Statute Laws that award the penalty of death sans clergy, from Edw. III to Queen Anne, with notes (London, 1817).
