What is the purpose of the ahnentafel form?
Use this form to make your ahnentafel or, in other words, a list of your direct ancestors in a fixed sequence of ascent.
How do I fill the ahnentafel form?
List yourself as No.1, list your father as No.2 and your mother as No.3, your paternal grandparents as No.4 and No.5 and the maternal grandparents as No.6 and No.7, and so on, back through five generations. Apart from No.1, who can be male or female, all even-numbered persons are male, and all odd-numbered persons are female.
The number of any person's father is double the person's number, and a person's mother is double the person's number plus one.
