Since Blogger added the static pages feature, I created a page just for surnames. A link (simply entitled "Surnames") is at the top of any Lincecum Lineage page you are on, just below the header. Once on the surnames page, you may click on a surname to be taken to all articles pertaining to that name. Also, you may click on the "Home" link to return to the main LL page containing the most recent posts.
I think this is an awesome feature, and I am so happy Blogger added it. I'm sure I will be creating additional pages in the future, so stay tuned!
