I've been trying to find a program that will show a family tree to illustrate the families I'm following on my maternal grandmother's side. On the right column on this page, I've added a link to World Connect that will direct you to my family tree. It's a little hard to navigate but I'll try to explain here:
After clicking on "Miller-Tittle Family" on the right, you'll be directed to my World Connect site. Enter the surname Tittle in the search block. Then click on "Tittle". Scroll down and click on William R. Tittle. Near the top of the page click on Pedigree and you'll see his ancesters.
