Looking through various search engines, I found a reference to the Hodgsons of Sisodorgue. On Nov. 20th 1802 they had several children baptized at St John's Chapel. FreeReg records the baptism, but names their residence as Six Darg. A darg or dargue referred to the amount of work that could be done in a day. It was a farming term, later used in mining.
Peter Bowes's book on Weardale, "Clearing the Forest" refers to the farm as one of those established as farming was expanded into the upper dale. On the map headed "New settlement in the Forest and Park 1660 to 1710" he marks the farm to the west/south west of Wearhead and calls it "Six Days Work", though in the text he also refers to it as Six Dargue. The farms near it are Stonedrass and Low Rigg.
As is usual in the Pennine dales, miners would also be farmers, with their families keeping the farms going when they were down the mines.
