Genealogical charting takes many forms from graphical displays to simple lists. Genealogists use a variety of charts to record, verify and publish data collected for each individual in a family. Geni incorporates aspects of various genealogical charting systems in a new graphical interface, the geni tree, while providing easy access to commonly used lists.
Ahnentafel or Sosa-Stradonitz System
Ahnentafel is a German term meaning "Geneological table" and refers to one of several numbering systems used to record individuals on a pedigree chart or in list form. Each individual is numbered based on their relation to the descendant, with the descendant being No. 1. All male ancestors are numbered evenly while all female ancestors are numbered oddly; the father being twice that of the descendant of each generation and the mother being twice that of the descendant of each generation, plus one.
- Paternal grandfather (father's father)
- Paternal grandmother (father's mother)
