600 years and a few family lines is a drop in the bucket, given that the number of ancestors we each have doubles every generation.
While it is good to know as much you can about your ancestry, if you had the power to go further back to see you ancestors 1,000, 2,000, or more years ago, I dare say we would find plenty of incest, rape, murder, kidnapping, slavery, etc, in the ancestors of every living human on Earth.
People will sometimes say they have famous ancestors. I once worked with a guy who said he was descended from. Alexander the Great.
