History
The suburb was named after the ancestral home of the Hon. John Watts-Russell (1825–75), who hailed from Ilam Hall in Staffordshire, England. He settled in Canterbury in 1850, arriving on Sir George Seymour and named his property Ilam.
The Ilam homestead was in the 1950s inhabited by the rector of Canterbury College, Henry Rainsford Hulme. In 1954 the homestead gained notoriety as Hulme's 16-year-old daughter Juliet was involved in the Parker–Hulme murder case. The homestead was used as a major location for Peter Jackson's film about the murders, Heavenly Creatures. The homestead has been the University of Canterbury Staff Club since 1971.
