I am interested in the Elizabeth "Betty" COOK, who married Isaac S. Mitchell. I am trying to find the parents of my gg-grandmother; Martha Mitchell(b, abt, 1849-50, TN) & her sister; Mary Mitchell, both living in Franklin/Johnson Co.'s 1867-1880. Martha married. Andrew Bench, 1868, Franklin Co. (I figure she lived in Franklin Co. at the time.) She died & he marr. her younger sister, Mary Mitchell in 1878, in Johnson Co. (his farm was there). The Mitchell's were fr. TN.
