"The History of Knox County, OH", p.718, refers to "Brush run (Run?) near Butler Township.." as the location where the parents of George Lepley (b. 1791) and Jacob Lepley (b. 1804) first settled in Knox County about 1804-1807. Can anyone give me a more precise location of where "Brush run" used to be, or the current name of "Brush run"?
