For the past few months, I have been compiling old records into an extremely large family tree in order to visualize the data. There are about 9,000 named people, plus some unnamed/placeholder "sibling of," "mother of," "father of," "child of," etc., bringing the total to 9,337 people at the time of asking this question. I understand that this software has limitations, and it would surely blow everything up if I were to see the entire tree at once. However, I was wondering if there was a method - apart from aimlessly clicking - to see the person with the oldest birth date on your tree, whether that be via search, a different window, or by some other method.
(Note: the vast majority of the people on this tree are dead, so the "Calendar" tab does not work. Also, I started from the middle, not from the top.)
