Explanation of the Ahnentafel Numbering System

The ancestor reports on FamousKin.com use 'Ahnentafel' numbering. This means that the starting person is always number 1. That person's parents are always numbers 2 and 3. Each ancestor's parents are calculated by multiplying their number by 2 for the father, and adding one to that result to get the mother. Except for the starting individual, males are always even numbers, and females are always odd numbers. To determine a person's child, divide their number by 2 and drop any remainder.
