Question: On the Internet I found a family tree for my family that goes all the way back to Adam and Eve. How can I prove this lineage?
Answer: You can’t. Lineages that go back to medieval times or earlier are always suspect; you need to fact-check the entire lineage very carefully. Medieval records are quite different from later records, and usually document only the wealthiest / most powerful families. Prior to 1200 A.D., there are very few written records at all. It is possible in some cases to track royal or noble lineages back a bit farther, and there are respected sources for doing that. However, before a certain point, there are simply no written records, even for royal and noble lineages. Because of this total lack of written records, the 1200 A.D. date mentioned previously is for almost everyone the end of the line genealogically speaking.
