Have you written your own story? Many genealogists spend so much time obtaining information on dead relatives and interviewing living ones that they neglect themselves?
Think about the things you wish your ancestors could tell you? Why they moved; why the voted; what they thought about certain events in their lives.
And when you have a list of things you wish your ancestors could tell you....answer those questions about yourself. Or at least the ones that apply to you.
If you describe your Civil War service to your descendants they might not be inclined to believe much of what you say about anything else (smirk).
