Hi. My g-g-grandmother was Sarah Tennessee Smith (Grayum) Her family lived in Clay County, Kilgore Twp Arkansas. Her father was George W. Grayum b. 1845. I don't know exactly where Cole Co. MO is but Clay Co. AR is right up at the MO/AR border. Take a look at the 1880 Census for Kilgore Twp. It's online. You may find some familiar names. Please let me know if this helps.
