I just ran across your Dixon query on the message board. It is a couple of years old, but in case you are still interested, I have been doing some research work for a friend who is a ggg-grandson of Shadrack Tootle Dixon and his wife, Judie Covington. Their daughter, Margaret Eugenia Dixon, married Joseph Columbus "Lum" Owen.Their son, Luther Cleveland Owen, is buried here in Grants Pass, Oregon. Luther is my friend's great-grandfather. I have more info, if you are interested.
Kind regards, Tony Lewis
