As an interesting aside, Benjamin Helm, the Confederate general from E-Town who was killed at Chickamauga, was married to Mary Todd Lincoln's half-sister. When Lincoln learned of this, he went into mourning.
They talk about the Civil War being "brother against brother" and KY really exemplified that - I think more than many other states. I think Mary Todd had several siblings that fought for the Confederacy while she was the First Lady for the Union.
