Each generation is marked by a thick blue line between our Young ancestor and his wife's name. As you scroll around the 13 Generation Tree, you may choose any generation and get more details by way of a more detailed tree. For instance if you wanted to see a more detailed tree of Willis and Mary Carter Everett Young, scroll down to the boxes that are next to each other and connected with a thick blue line. Simply click on either name and you will be taken to a page with that detailed tree.
