Puzzilla.org uses the Family Tree in FamilySearch.org and shows you Research Patterns in your Collateral Lines.
Looking for new relatives to take to the temple? Is your pedigree picked over? Is there really no work left for you and your family to do? The free Puzzilla.org Descendants Viewer lets you see hundreds of descendants of your ancestors from an aerial view. Compact symbols reveal patterns of incomplete research. You can pick up where prior research left off. Click on a pedigree ancestor and Puzzilla will show you their descendants, revealing pockets where more research might lead to spouses, children, and generations of relatives waiting for you to find them.
Watch the two videos on the site to help you learn how to use it. You should be able to view them at the Family History Center. Here is the link: puzzilla.org/. Try it out and let me know how you like it and if you have other questions.
