I live in Decatur too. Your quartz finds look like Swift Creek period stuff to me. I find a lot of stamped pottery shards. You should go to some of the Greater Atlanta Archeological Society meetings at FernBank. The president and vice-president are experts on local points. There are some good books on the Swift Creek culture on Amazon.
City of Decatur is a great place to live. It was rough twenty years ago, but is very safe now. The taxes are a killer though.
