If you click on the Family Trees and Tools tab on a profile page, then scroll down to Ancestor list and click on that, you will get the Ahnentafel/Ahnenlist for that person. For your ancestor Andrew Lemuel Adams, is is HERE. The list includes the Ahnentafel numbers, which are the key to navigation. Except for the first person on the list, who is always #1, all males have an even number, and all females have an odd number. Number 2's father is #4, his mother is #5, and his grandfather is #8, etc.
