I am from this area and happened to just be browsing the posts here. I did a little looking around and only found Thomas J Jones and Sara in the 1860 Census. It is here: http://www.mindspring.com/~ednab/cen60f.html
. This site also might be helpful for info of Milton Co. http://www.mindspring.com/~ednab/index.html
There were a lot (and still are) of Jones around the area. I grew up when this area was still small and now it is a very booming town and growing too fast!
This area is now Fulton County, about 30 miles north of Atlanta. I don't know what area you are from, but if you find any resources in Alpharetta, shoot me an email and I would be happy to try to gather the info for you since I am here. A lot of people have helped me in that way.
