Painter using a variety of media, notably watercolour, and teacher, born in Carmarthen, who lived for many years in Kent, settling at Rainham. He studied at Maidstone College of Art and the Royal Academy Schools. Went on to teach watercolour part-time at Eton College. In 1994 his meticulous depiction of terrace houses, Chatham, won the £15,000 first prize in The Singer & Friedlander/Sunday Times Watercolour Competition. Grey-Jones had gained an award in 1992 but, realising the rules excluded paintings previously shown in London as ineligible, he withdrew and the prize went to another painter.
