• From Mines and t'Miners - A History of Lead Mining in Airedale, Wharfedale and Nidderdale", by J. M. Dickinson
  • "Alcock was a solicitor in Skipton and was concerned with the Turnpike Trusts, James Tennant and Henry Wrathall were Trustees of the Grassington to Knaresborough Turnpike road in 1758."
  • "Conistone Moor Mines.

    By 1772 some miners had drifted over the moors from and up to 50 workings were in operation on the various veins. During the 1800's several of the Moor Mine Promoters, Overend, Tennant and Wrathall, to name some, took leases and formed partnerships to work the veins at the eastern end of the moor."

• From P. O. Directory Vol. I, West Riding of Yorkshire 1857:
  • Under Linton: Wrathall Stephen, farmer and Cattle dlr.
  • Under Grassington: Wrathall, William, farmer and butcher

Henry Wrathall's will (dated 1720) mentions:

"and a third part of the Water Corn Mill which now my said father enjoys"

In "What to See in Grassington, Linton and Threshfield", by Elizabeth Raistrick, the author does a walk round Grassington and describes the buildings that she passes. Having gone along Chapel Street (see map of Grassington ), she names the last house as Town Head Farm, and then says:

"We now turn left and pass Scaw Ghyll (a deep wooded ravine or a narrow mountain torrent), on the site of, and partly incorporating, the Old (Manorial) Mill, based on a small stream which has now gone underground. On the right we pass Cove Lane leading towards Grass Wood, with Bill Ing Lane straight ahead and Garrs End Lane to the left."

So with reference to the map of Grassington , this gives us some idea of where there was a "Water Corn Mill" - possibly.
