Hi Dora. Here are a few associated with Columbia County: Cheatham, Green, Clark, Reeves/Reaves, Baldaree, McDermott, Powell, Flinn, Burgess, White, Clemens/Clemons, Bryant, Alderidge, Stocks, Langston, Lewis, Millican and many more that I can't take off the top of my head right now. Try to keep them all in mind when searching, because you never know when one of them might pop up. Seeing the name clicks and then I get a picture of the line in my mind. Thanks for your help and let me know if I can help you. Peter and David Aldridge are my tie to the Alderidges. One of them married Caleb Powell's daughter if I am not mistaken. Thanks again, Dan.
