Descendants Viewer 6: Research Patterns in FamilyTree Collateral Lines.

The Puzzilla Descendants Viewer is a combination of free basic services plus subscription premium services that help researchers see descendants in FamilyTree using compact symbols that reveal patterns of incomplete research and other work in collateral-lines. Names and details appear as you move the pointer over the symbols. Premium Services, available by subscription, provide hints, sources, possible duplicates, incomplete ordinances, search and other functions to help evaluate the quality of the research in the tree and add evidence to make it stronger.
