Margaret and Garmon's twins David and Peter Garmon Jones were born on 18 June 1930 [Conway 1930, 3rd qt]. They were educated at Ellesmere College in Shropshire; they played heralds in the school's 1945 production of Richard II.
David Garmon-Jones (1930-2000)
After leaving school David served in the Royal Army Pay Corps., initially as a cadet but in July 1949 he was given an Emergency Commission, becoming a 2nd Lt.; presumably this was during his National Service. He originally lived in Southport but by 1960 he was working for the Overseas Branch of the Midland Bank, 122 Old Broad Street, London. That year he made six business trips to New York sailing first class, mainly on Queen Elizabeth, but occasionally on Queen Mary and once on The Mauretania. His occupation was generally recorded as 'banker'. In 1971 he married Helen Mavis Binns (née Donnelly) [Southport 1971, 4th qt] who had been born in 1934 in Heywood, Lancashire, and they had a son who is married with children.
David died in 2000, aged 69 [Sefton North, Jan 2000].
Peter Garmon-Jones (1930-1994) M.R.C.S., Eng., 1954, L.R.C.P. Lon., 1954, M.B., B.S. 1954, U. Lon.
It would appear that Peter spoke in debates at school. The Ellesmerian of January 1947 reported that he was the main speaker opposing the motion "That in the opinion of this house the various churches of the Kingdom should be merged"; the motion was defeated. After qualifying as a doctor at London University, Peter married Margaret Sylvia Porter in 1955 [Conway, 1955 3rd qt]. She was born on 2 March 1930 and died in 2005, aged 74 [Chiltern, Feb 2005].
During his National Service in the Royal Army Medical Corps Peter was made a Lieutenant in 1955 but was promoted captain the following year. From the late 1950s until the 1970s he was a GP living along the road from his surgery in Orrell Road, Wigan. In 1972 he was cosignatory of a letter published in the BMJ. Peter must have played an active roll in the St John Ambulance Brigade, work which was acknowledged in 1977 by his being made a Serving Brother of the Most Venerable Order of the Hospital of St John of Jerusalem.

Peter died, aged 63, in 1994 [Wigan Feb 1994]. He and Margaret had two sons. There are living descendants.
