Sir John Morris, 1st Baronet (15 July 1745 – 25 June 1819), was a British industrialist, active in copper-smelting and coal-mining in Swansea, South Wales.
John Morris had four older siblings: Robert (a barrister born c. 1743, a supporter of the radical politician, John Wilkes, who died unmarried c. 1797), Bridget, Jane and Margaret,[2] who as Margaret Desenfans became one of the co-founders of the Dulwich Picture Gallery The family expanded their copper-smelting and coal-mining interests in the Tawe valley throughout the remainder of the eighteenth century.
Clasemont was their home in the Clase or Clâs part of Morriston which had been taken down before 1849 when the locality was summarised by topographer Samuel Lewis.
In 1776 his sister Margaret Morris married the Frenchman, Noel Joseph Desenfans; they and Francis Bourgeois would eventually build up an art collection which became the basis of the collection at Dulwich Picture Gallery in London.
His older son married the daughter of the 5th Lord Torrington and continued the male line - he had a Navy Commander and General among the less senior of his four sons and the title devolved from one branch to another to a Morris descendant of the Commander living in Georgetown, Ontario.
