Born in Jesmond, Hugh de Chastelai Casley was the second child and only son of Wilbraham John Braddick Casley, civil engineer, and Mary Anne Eleanor Casley. They came to live at 5, St. Vincent Terrace, Coatham. Hugh had two sisters: Hilda, two years older, and Phyllis, two years younger. He attended Coatham Grammar School as a day boy from April 1896 to December 1899, when he went on to Charterhouse, the public boarding school in Surrey, where he remained until 1904. He won at least one school prize whilst at Coatham: at the end of his year in Form II, in July 1897, he was presented with a volume of Charles Lamb’s Poems and Essays as a prize for drawing. He later returned to the North East to train as a construction engineer in the steel industry with Head, Wrightson & Company, later moving to Dorman, Long & Company. He became a member of the Cleveland Institute of Engineers. He continued to live in the family home in Coatham with his parents and younger sister Phyllis before joining up in September 1914.
