Dear Scott - My 3x Great Grandfather was also in the 45th Ohio - Company I, with your 2x Great Uncle. His name was Ellis McFarland. I have a collection of his letters that he wrote to his wife, my 3x Great Grandmother while he was in the war. In a few of these letters, Ellis actually mentions your Uncle Wilson. In fact, I think they may have been friends. In this collection, there is also a letter from William Norman that references your uncle dying at the Battle at Philadelphia, TN on October 20, 1863. Wondering if you or anyone reading this has any additional information on the Battle of Philadelphia, TN or the 45th OVI besides what is on their website. Anxious to hear from someone.
