I'm a newbie to the Magna Carta Project and like you I've often wondered how far donwn the descendant line do I go. While the Magna Carta is for tying a Surety Baron to a Gateway person, and that I fully respect. However, for me personally, I enjoy following the related Gateway person back to myself. It is a time consuming and trying effort, but I assue that it is ok to persue a line to your satisfaction. As I love History and really enjoy the challeng of tying my family back to someone I only read about in school. It just brings history alive.
