Ahnentafel Charts

An Ahnentafel (Ancestor Table) is used to show ancestry using only text, through a specific, fixed numbering scheme.

This is a typical pedigree chart:

Note the numbering sequence. Each individual person is numbered, and that there is a mathematical relationship between parents and children. Each father's number is always double that of his child's while the mother's number is always double that of her child's plus one.


An ahnentafel would depict the same ancestry as text:
