Sir Carron Greig - Telegraph This was the world into which Henry Louis Carron Grieg was born on February 21 1925; he was to spend much of his childhood and adolescence at Thatched Lodge in Richmond Park, a grace-and-favour mansion (now Princess Alexandra's home) that came with his father's appointment in 1932 as deputy ranger of Richmond Park. Carron was educated at Eton, and on leaving school in 1943 he went straight to Sandhurst. As the outstanding cadet of his intake he won the shortened wartime course's "belt of honour," which was later autographed for him by his father's friend General Eisenhower. He was commissioned into the 3rd Tank Batallion Scots Guards, whose officers included Willie Whitelaw and the future Archbishop Robert Runcie. His unit landed in France in July 1944; he served as an intelligence officer in the advance across the Low Countries and in mopping-up operations in Germany, and was demobilised as a captain in 1947. Army records showed him to have been a capable officer who never complained, whatever the task or hardship. In later life he was equally uncomplaining when the IRA twice blew the windows out of his office - first when the historic Baltic Exchange building was destroyed in 1992 and a year later when Bishopsgate was blasted - and when he was diagnosed, at about the same time, with the onset of Parkinson's disease. During his senior career Greig was also a director of Williams & Glyn's Bank and its owner the Royal Bank of Scotland, and of the shotgun maker James Purdey & Sons. He was vice-chairman of the Not Forgotten Association for wounded servicemen, a governor of Atlantic College, and chairman of the Schoolmistresses and Governesses Benevolent Institution. He was appointed Deputy Lieutenant of Hampshire in 1992 and was made KCVO in 1995 when he reached the retirement age for Gentlemen Ushers - thereafter becoming an Extra Gentleman Usher. Royal service continued into a third generation: his son Louis was a page of honour to the Queen, and his daughter Laura Lonsdale was a lady-in-waiting to Diana, Princess of Wales. It was at his farm near Fleet that Carron Greig was most at ease. After a day's work in the City he could be found happily plucking turkeys, feeding pigs or inspecting his fine herd of Red Poll cattle. He also maintained, as a base for sailing holidays, a former sea tavern on the Culbin Sands near Findhorn in north-east Scotland which Sir Louis - a founder member of the Royal Findhorn yacht club in the 1920s - had bought on a whim at the end of the war: "Am told only a madman or a poet would buy," read a telegram to Carron in Germany. Have bought. A voracious reader and autodidact whose knowledge covered a remarkable range, Carron Greig assembled one of the most complete collections of Trollope first editions in private hands. He married, in 1955, Monica Stourton, a granddaughter of Lord Mowbray, Segrave and Stourton. She survives him with their three sons and one daughter. The third son, Geordie Greig, is the editor of the Mail on Sunday and former editor of Tatler. Sir Carron Greig, born February 21 1925, died July 11 2012
