Welcome, Zandra! We're happy to have you visit WikiTree and hope you will consider joining and adding your branch of our one family tree.
Since you mentioned A.J. Jacobs I thought you might want to look at his profile page. You can click on the Family Tree &Genealogy Tools tab to see his family tree (you can do this on any profile in WikiTree). You also can go to this link to see how you are connected to A.J. and to Queen Elizabeth II. No connection shows yet sine you have not yet added your family.
If you have not yet viewed the WikiTree help pages, you may want to look at the How to Use WikiTree help page. Please take your time to look around and consider if you want to become a member.
