I have researched my ancestry for almost 15 years and I can tell you this that you want live long enough to end your tree. That's how big it is and it keeps growing. If you know where to look. I have posted the lasted 3 years on here much info. You have to study all history and that alone can take years and it don't stop. For every one ancestor starts a whole new tree. All over the world. It's no joke. In order to get your truth you have to follow their lies.
