If you research your ancestry long enough, chances are you will come across at least one black sheep of the family. They may have been imprisoned or even executed for a crime, been committed to an insane asylum or led lawmakers on a merry chase looting the high seas. It's not unusual to run into a brick wall with these individuals since many families would pretend the person didn't exist or make up a tamer story to cover up why the person no longer lived with them.
