Francis Coulton Smith died in Brisbane on 24 May 1981. His death notice in The Age on 25 May 1981 might give clues to relatives (the fact that it was published in The Age is a clue to potential relatives or friends in Victoria). It's a fairly large net to be looking for 'Smith' unfortunately.
He was born 31 October 1908 at Mansfield, the son of William Coulton Smith (a teacher who lived at 38 Wheatland Road, Malvern, died September 1945) and Rosalie Myrtle Mummery (who survived her husband, died 18 March 1972 in Wangaratta). I cannot find a record of their marriage in Victoria or NSW.
According to Victorian records, Francis Coulton Smith was the only child born to William and Rosalie Smith born in Victoria from 1880 to 1919.
Francis Coulton Smith married Alice Langlands in 1952 in Victoria. (Alice had a sister Molly, their mother died on 1 January 1950).
He appears to have moved to Queensland.
We don't know if they had children
