An ancestor chart is a printable template used to show the five generations of a family. When filled out with a name, parents, grandparents, g-grandparents, and g-g-grandparents, this five-generation pedigree chart will make a lovely present. This is a great way to get kids interested in their family history. A third of your family consists of your grandparents and their siblings. The first generation is at the top of the family tree, followed by their children (second generation), and so on, with each consecutive generation receiving a higher number - third, fourth, fifth.
