Thomas Martin resigned his pastorate at the Great Meeting (Independent), Yarmouth (he had become a Unitarian, it appears, by that time) in 1798. He removed to Liverpool, where he became a wealthy merchant, owner of Calderstones Park (1807-25), and eventually Secretary of the Royal Liverpool Institution, before becoming a bankrupt in 1826. He was the author of Zetemata Dianoetika: or a View of the Intellectual Powers of Man (Liverpool, 1819), a paper Martin delivered before the Literary and Philosophical Society of Liverpool. Martin maintained his friendship with William Taylor into the 1820s. He is probably the same Martin who dines with Godwin at the Aldersons house in London (along with a Taylor, Marsh and Bartlett Gurney, a Quaker banker from Norwich) on 28 June 1794. See J. W. Robberds (ed.), A Memoir of the Life and Writings of the Late William Taylor of Norwich, 2 vols (London, 1843), vol. 2, p. 297.
