Information from the obitiary of Erwin Koberstein
The ancestry report uses 'Ahnentafel' numbering. This means that a person's parent's numbers will be twice as large as the person's number. So if someone's number is 15, her father will be number 30, and mother will be 31. Her child will be number 7.
