Thanks for the info on this book - I ordered it from Amazon this morning.
I had ancestors & relatives in Morgan County, Tennessee (northwest edge of East Tennessee), who fought on both sides. No brothers fighting brothers (that I'm aware of), but lots of situations where first cousins or uncles/nephews were on opposite sides. My great grandfather, along with a couple brothers, at least one uncle & several cousins enlisted in 16th TN Cavalry (CSA). Lots of his first cousins & other uncles were in various Union outfits, including a couple in "Tinker Dave" Beaty's Scouts. After the war, most all who fought on CSA side were NOT welcomed home - in fact most were told not to return on penalty of death, and they settled in surrounding counties (Roane, Rhea, Meigs, etc.) where folks were a little more friendly to ex-CSA soldiers.
I have always been curious why people in the same area, with same background and closely related would have had such varied political views. In this area, it had nothing to do with slavery. Although many of my ancestors/relatives owned 1,000 acres or more (from early grants), the land was pretty much worthless for anything other than subsistence farming, and all were too poor to own any slaves.
Maybe the book will answer some of my questions, or maybe Dr. Fisher will answer some on this forun.
