Born: In 1890 in Glasgow, Lanarkshire, Scotland.
Family: He was the eldest child born to Andrew McLaren Clelland, a bread vanman, and his wife Margaret (nee Stewart). He had at least one sister, Margaret; identification of further siblings has not been possible due to the unavailability of Scottish records. There is a 1914 electoral register record for a James S Clelland living at 184 Slatefield Street, Glasgow (this may relate to the right man). In 1915 he married Dorothy Muriel Whiston in Whitchurch, Shropshire and together they had two daughters, Janet and Sheila.
