Except for a couple of years in Tennessee, I've lived my whole life in Kentucky. Like most Kentuckians, my ancestors fought on both sides. Because of our geographic location, customs, and speech, I've always considered myself a Southerner. Personally, I have never really looked at being "Southern" as necessarily related to which side my people fought on during the Civil War. I may offend some on this board, but I do not believe that the entire South was a united group of people wishing to start their own country, the Confederate States of America. There were quite a number of Southerners in the 11 official Confederate states who fought in Federal units or simply refused to support the Confederacy.
Just my two cents worth!
