Born at Barrowford, Lancashire on 14 February 1869 Every-Clayton studied medicine at Guy's Hospital, graduated MB BS with first-class honours in 1895 and took the MD and FRCS in 1896. After appointments as house physician and obstetric medical officer at Guy's and clinical assistant at the London Fever Hospital, Every-Clayton entered general practice in 1898 at Emsworth, Hampshire where he stayed for seven years. In 1905 he moved to Clevedon, Somerset where he worked for seventeen years. He was honorary medical officer to Clevedon Cottage Hospital, and served a team as president of the Bristol Chirugical Society. During the first world war he served at Etaples in the RAMC with the 26th General Hospital, which he had helped to form. A serious accident handicapped him for a year about 1921 and during this time he lived at Mullion, Cornwall. On recovery Every-Clayton took over two practices at Tetbury, Gloucestershire. Three years later he moved to Sunbury-on-Thames, where he was divisional police-surgeon. He finally practised at Minehead from 1930 to his retirement in 1945. Every-Clayton was a fine example of the general practitioner surgeon; a countryman, he particularly loved Exmoor, and he had great botanical knowledge. He married Dorothy Anne Elizabeth, daughter of Edward Bennett of Marsden Hall, Colne, Lancashire, and they had a son and a daughter. After retiring Every-Clayton lived at Wood End, Sandhurst Road, Wokingham. He died there on 18 November 1954 at the age of 85, less than a month after the death of his wife.
