Who was the White Woman of the Walhonding River?

If you visited the area of Roscoe Village at Coshocton, Ohio near the confluence of the Tuscarawas, Walhonding, and Muskingum Rivers, you’ve likely seen “White Woman Street,” or markers with the name “White Woman’s Rock,” or “White Woman’s Town.” It would be natural to wonder who or what those names pertain to or whether they even referred to a real person.
