From William T. Price's Historical Sketches of Pocahontas Co, WV (reprinted by McClain Publishing, Parsons, WV, 1963; originally published by Price Brothers, Marlinton, WV, 1901):
Henry Dilley went over to John Sharps, the early settler of Frost, often enough to persuade his daughter Margaret to have him for better or worse, and they were happily married and settled on Thorny Creek. As long as Dilley's Mill be known, his name will never be forgotten. Mr. Dilley never doubted the truth of the bible, especially that place in Genesis, where it speaks of the ground bringing forth "thorns and thistles." He had enough of these things to contend with on his Thorny Creek land where he settled, opened up a home, and built a mill. It was one of the best of its kind for that day, and it's successor keeps up a good reputation as Dilley's Mill yet. Men may come and go, but the beautiful perennial stream that was utilized by Henry Dilley still goes on its useful service for the benefit of his children's children and a great many others far and near.
