genealogytree – Pedigree and genealogical tree diagrams

Pedigree and genealogical tree diagrams are proven tools to visualize genetic and relational connections between individuals. The naming (tree) derives from historical family diagrams. However, even the smallest family entity consisting of two parents and several children is hardly a mathematical tree — it is a more general graph.

The package provides a set of tools to typeset genealogical trees (i.e., to typeset a set of special graphs for the description of family-like structures). The package uses an autolayout algorithm which can be customized, e.​g., to prioritize certain paths.
