Possibly refers to the gully midway along the western side of Hassans Walls and the eastern side of the First Lookout, Lithgow. It may have been named after Nellie Constance Hoskins, who died aged 18 years, 1914. Nellie was the daughter of Charles and Emily Hoskins who had given 50,000 pounds to build the Hoskins Memorial Church (Presbyterian) at Lithgow.
