Even my Unionist GGF, member of the Union League, owned eight slaves, who were confiscated by Alabama, along with the rest of his property. I have nothing from him past 1867, which I hate. All the rest of the little diary is taken up with commercial transactions. In a personal/family tragedy, my uncle let himself get swindled out of the family farm in Berlin (near Holly Pond). Many precious family photos and documents were placed in a leaky outbuilding and were destroyed. I know my GGF sued the "new" state of Alabama twice for compensation, but they successfully defended on the grounds that the confiscation was performed by an illegal, rebel regime...
Edit: Ironically, my GGF had promised his slaves manumission, no matter the outcome of the war. By being confiscated in 1862, they remained slaves for several more years. I'd love to know if they returned to him at the end of the war. He was fairly comfortable, financially...
