John Thornton (1720-1790) inherited a large fortune, which he invested in trade, and used to provide generous support to the first generation of 'Evangelicals' and to circulate immense quantities of bibles and religious books throughout the world, many of which were printed at his own expense. He also bought advowsons, which he used to appoint deserving clergymen, such as John Newton (1725-1807). In 1753 Thornton married Lucy (1722-1785), only daughter and heiress of Samuel Watson of Kingston-upon-Hull.
