Tiny Ahnentafel - Ancestor Table
To visualize the numbers, consider this typical pedigree chart:
8. greatgrandfather 4. paternal grandfather-| | 9. great grandmother 2. Father--| | | 10. greatgrandfather | 5. paternal grandmother-| | 11. greatgrandmother | 1. Person-| | | 12. greatgrandfather | 6. maternal grandfather-| | | 13. greatgrandmother 3. Mother--| | 14. greatgrandfather 7. maternal grandmother-| 15. greatgrandfather
Carefully observe the numbers in the above chart. You will notice that every person listed has a number and that there is a mathematical relationship amongst parents and children. The number of a father is always double that of the child's. The number of the mother is always double that of the child's plus one. The number of a child is always one-half that of a parent (ignoring any remainder).
In the above example, the father of person #6 is #12 (the father is double the child's number). The mother of #6 is #13 (the mother is double plus one of the child's). The child of #13 is #6 (the child is always one-half the parent's number, ignoring remainders).
Now, let's take the above chart and write it in ahnentafel format:
1. person 2. father 3. mother 4. paternal grandfather 5. paternal grandmother 6. maternal grandfather 7. maternal grandmother 8. great grandfather 9. great grandmother 10. great grandfather 11. great grandmother 12. great grandfather 13. great grandmother 14. great grandfather 15. great grandmother
Notice that the numbers are exactly the same as in the pedigree chart.
