If his first wife had died, maybe he went to live with his parents especially if he had small children to take care of. In 1870 Lee Co. was formed from Owsley, Breathitt, Wolfe and Estill Co. But supposedly he was married in Nicholas Co. How did he happen to meet his new wife I wonder. Nicholas was formed in 1799 from Bourbon and Mason Co. But Robertson was formed in 1867 from Nicholas, Bracken, Mason, Fleming and Harrison Co. So maybe you could check Robertson and Lee as well. I know I am just adding to your work. Lee has no censuses on line. I wonder why they came so far south to Casey for that short time?
