Born on 28 June 1901 at Coolgardie, Western Australia, eldest son of Adelaide-born Elphinstone Davenport Cleland, mine-manager, and his second wife Anne Emily, née Mackinnon, from Scotland. On 18 December 1928 he married Rachel Evans at St George's Cathedral, Perth, Western Australia. Energetic, with broad interests and deft social skills, Rachel complemented his dour, sometimes gruff, manner, and eased contact with diverse people. She was appointed D.B.E. in 1981.
