The Civil War divided the county, just as it did the nation. No one felt that division more acutely than Sheriff Thomas Jefferson "Mac" McQuiddy who took office in 1860, was arrested by Union Soldiers around July 4, 1861 as a secessionist. His replacement was Thaddeus Koscusko [Koscuisko?] Beal, who would finish the rest of McQuiddy's two-year term, then enlist in the Union Army. Sheriff McQuiddy's son would later be arrested in Illinois, near the Missouri border, along with several other men and some 'pilfered' horses. Spoils of war?
