It's a death notice in the classified ads, not a full obituary.
"ROBERTSON, William Duncan MBE passed away in his 92nd year on 27th July, greatly missed by his daughter Mrs F Erskine-Murray and son-in-law, of Cautherly Lane, Amwell, Ware, Herts and also by his grand-daughters, great-grandsons and friends. Funeral at Great Amwell Church on Saturday 30th July at 11 a.m., no flowers please." Source Citation: "Deaths." Times [London, England] 28 July 1983: 26. The Times Digital Archive. Web. 11 July 2017.
Odd that he should be described as MBE if he also had an OBE; OBE is a higher honour than MBE.
There seem to have been two daughters and a son who died in infancy. I can't name them because the daughters may still be living but you can look them up at
