Cindy, William Harrison Car(e)y might be listed in "Loyal Mountain Troopers - The Second And Third Tennessee Volunteer Cavalry In The Civil War" by Charles S. McCammon. Serendipitously, the book is published by the Blount County Genealogical and Historical Society and information about it is on the Blount County webpage. The book contains a listing of all of the soldiers in all the companies of the 2nd & 3rd Regiments of the Tenn Vol Cav. Unfortunately, there is no index of that listing and the names aren't listed alphabetically. Consequently, it would take quite a bit of time to look through the list. However, the text is VERY interesting. Good luck to you. Stan
