The son of the elderly
George Chichester, 5th Marquess of Donegall (1822–1904), Chichester was educated at the
École nouvelle de la Suisse romande,
Eton, and
Christ Church, Oxford, and took up a career in journalism. For many years he wrote a column in the
Sunday Dispatch under the title "Almost in Confidence". He made regular contributions to the
Sunday News and
Sunday Graphic, and also held a staff position on the
Daily Sketch. Donegall parted from his wife after 10 years, and in 1962 moved to Switzerland. In 1968 the Marquess was granted a divorce under Swiss law and in that same year he married Maureen McKenzie (née Scholfield), daughter of Major Geoffrey C. Scholfield of
Birkdale, Lancashire, and former wife of Douglas McKenzie, whom she had married in 1947. Donegall resigned as president of the
National Canine Defence League in 1957. He had been connected with the League for more than thirty years. ==Death==
