Both also resided sometime in the Australian state of Queensland. Prosper Thomson's wife, Queenie, survived a plane accident in Queensland not long before her husband, Prosper (a motor vehicle enthusiast) and her were divorced. Jessica nee Harkness from Sydney followed Prosper to Glenelg with Jessica doing so via her parent's residence in Mentone. Mentone is where Prosper and Queenie resided before moving to Queensland. Alf Boxall residing in Sydney is somehow involved.
