John Ernest Greaves

John Ernest Greaves CBE (30 November 1847 – 27 February 1945) was a wealthy Welsh slate mine owner and Lord Lieutenant of Caernarvonshire.

He was born on 30 November 1847 at Tan-yr-allt, Tremadog, the son of John Whitehead Greaves, who had developed the slate industry in the area. He spent much of his childhood at Llechwedd, where his father had created the Llechwedd slate mine and was educated at schools in Warwickshire, Edinburgh and Dorset before going to Worcester College, Oxford, where he matriculated in 1867. On his father's death he inherited a half share in the business and made his brother Richard Methuen Greaves the General Manager. They later turned the business into a limited company with himself as Chairman and his brother as Managing Director.

He was appointed High Sheriff of Merionethshire for 1884 and for Caernarvonshire for 1885. He was also a Deputy Lieutenant for Caernarvonshire. In 1886, he was appointed Lord Lieutenant of Caernarvonshire, the first commoner to hold the position, serving until 1933.

He had inherited the family home at Bron Eifion, near Criccieth, but in 1893 also bought the Glan Gwna estate near Caernarfon, rebuilding the hall.

He was very involved in public affairs, including President of the North Wales branch of the NSPCC, Chairman of the Quarter Sessions and Alderman of Caernarvon County Council. He had a particular interest in nursing standards and from 1898 was on the Council of Queen Victoria's Jubilee Institute for Nurses and was Chairman of the North Wales Nursing Association.

He died on 27 February 1945. He had married Marianne Rigby (1851-1934), with whom he had a daughter Dorothy (1876-1963). He left Glan Gwna to Dorothy's elder daughter, also Dorothy (1906-1966), who in 1930 in Fiji had married William Stanley Flower (1902-1940), elder son of Stanley Smyth Flower.

Greaves was appointed a Commander of the Most Excellent Order of the British Empire and in 1931 a Commander of the Most Venerable Order of the Hospital of Saint John of Jerusalem.
