Looks as though you've made some good suggestions for research and I'll try to locate the books by the authors you've mentioned. By the way, in any of your research, did you happen to read about a Confederate soldier by the name of Marcellus Jerome Clark? His nickname was "Sue Mundy", and he was captured by Union troops in a barn near the community of Union Star, which might have been called "Jackeysburg" during the war Between The States. Union Star is in northern Breckinridge county near the Ohio River. Clark was a young man in his early twenties, and was taken to a Union prison in Louisville, Ky, where he was tried and convicted of guerilla activities. Even though he protested that he was a Confederate soldier in a regular unit, he was still hanged as a guerilla. Though I haven't researched this, there is a possibility the he might have ridden with Quantrill.
