I have received the death certificate from Western Australia which correctly identifies William Wainwright as the son James Wainwright and Ann Maria Hughes
He died of Lobar Pneumonia on July 11, 1916 and was buried two days later at Wagin Cemetery. He was 45 years old. He is listed as a farmer and the place of death is listed as Pingarning East, Dumbleyung. The residence information was supplied in writing by his brother, George, whose address is listed as simply, Pingarning.
The certificate lists Williams birthplace as Manchester, England, and that he had been in Western Australia for six years.
His death was registered at Katanning on July 17, 1916.
The occupation of the father, James, is listed as "farmer," and this is most intriguing, because we have never seen James described as a farmer before, and this makes me suspect that the family story of James accompanying his children to Australia is true! And most likely he was working on the farm with William and George when William died.
