Do you know a lot of things about your history and ancestors? I don't. I only know that I had a great-great-greatmother who was severely mentally ill and burned her own house down because she saw a snake in her sheets. We don't know for sure if she was just hallucinating or not.
I know an immense amount of information regarding my family tree. It is absolutely overwhelming. My ancestors were first settlers in many parts of North America so there is a great deal of documentation.
