Walt, I'd go looking for Mahala. She might give you clues to what happened to the rest of the family. I'd check for her on later census' in Mo. Did she live to grow up and marry? Is she buried in that area of Mo.? Look for the family she was with on the 1860 census. By studying them, it may lead you to her, and through her, to the other siblings. I've had problems with direct ancestors and came across the answers by researching their siblings. Good luck. Christine Downing searching for Dameron/Damron, Coulter and Benson of Henry Co., Mo
