Genelines lets you create a color-coded descendant timeline chart, where each descendant branch of the family tree is assigned a different color. This lets you visually show how people are related.
In this example, the researcher, attending a family reunion, printed name tags of the same color to help people see where they fit on the family tree in relation to their cousins. He also displayed a wall chart version prominently for all to see.
The Full Descendant Timeline can also highlight family lines where more information is needed. In this example, there is little information for Sarah, Jonathan and Mary Alden as compared to others. These could be targeted for further research.
