The best way to help is to become one of us - A WikiTreer.
This is a free website so there is no cost. What are we about? We are trying to build a collaborative, single, world wide, family tree. So when you volunteer you can add your family and connect to your grandpa, James Deaton.
It would be great if you have information or sources to add. Then after you connect, try and see how else you connect by adding/working on the rest of your family tree.
That's a good start, and once you get that far, you are already learning to climb and scamper around this big ole tree of ours, like the rest of us!
