The NLS (the National Library of Scotland) have a full collection of Scottish maps, they do have also several years of (out of copyright) Ordnance Survey six inch and one inch maps covering England.
If you go to the LINKS page on my website it will give you the link to maps that cover Thoralby and other places. You can move around them by grabbing and pulling, zooming in and out. You can even print copies. If you want to explore the full NLS collection click on the NLS link, on my website.
Below is the O.S. map for Bishopdale from Myres Garth to Smelter (I have had to divide Bishopdale into 3 sections).
Below is the second section, New Gill to Lon Ridge. I have underlined all the scattered farms which make up the township of Bishopdale. The farms are: New Gill, Dada House, The Rookery, Scar Top, West Newhouses, Ribba Hall, Myres Garth, and Long Ridge. Smelter. The School is also listed, the Old Lead Mine, numerous Sheepfolds and a Sheepwash. The Limekiln is no longer listed, but the Stepping Stones are. In addition there are numerous field barns named.
