Ahnentafel chart| There are different formats that a Family Tree might take. Depending on the style of the chart that you are using, it might show five, six, seven, or even more generations. Some family tree charts get so full of information that it can be difficult to understand exactly how one ancestor relates to another one, or how either of them relate to you. Instead of using the typical, tree shaped, family tree design, try using an ahnentafel chart instead.
