 The site on which Asquith Boys High School was built was originally a citrus orchard owned by the Fear family, a Hornsby pioneer family.The name ""Asquith"" from which the suburb north of Hornsby, and subsequently the school, takes its name, was named in 1915 after the wartime Prime Minister of the United Kingdom, H. H. Asquith, who was later made the Earl of Oxford and Asquith.Before the land was acquired by the New South Wales Government in the 1950s, the land had become a cattle and horse paddock.
