JE Jones, from the information I have found over the years, was in the Yednalue area in the mid-to-late 1880s; I have him applying to occupy a house at Yednalue Station in 1885, and writing about the poor state of the road from Yednalue to Curnamona in 1889. Perhaps he was a hawker - he wrote a letter of complaint about unlicensed hawkers in 1892.
From 1896 to 1912 he seems to have been a storekeeper at both Blinman and Parachilna at various times. Parachilna was the railway siding for Blinman, so it is possible that he had stores at both - or a store at Blinman and an agency at Parachilna. He leased a block or two at Parachilna (or in the Hundred of Nilpena, which includes Parachilna township).
From 1912 to 1915 or thereabouts he was a member of the Angorichina Vermin Board, a local board responsible for building and maintaining the vermin fence around the Angorichina and Artimore pastoral leases - just to the east of Blinman.
I haven't ever checked the Sands and MacDougall Directories for entries for him over that period.
