Which data structure is used for family tree?
A general graph structure would be the best (a tree being a specific form of a graph). The edge would carry the relationship. Then you can run a path finding algorithm (like good old dijkstra) only on edges which represent blood relationship.
How is a family tree structured?
A family tree is a visual representation of a person’s lineage, tracing relationships to common ancestors.

What is the core of the family tree data model?
As the model illustrates, the core of the Family Tree data model are the individual persons that, linked together by relationships, create the Tree. The purpose of the other data objects is to give support and detailed information about the person, relationships and the research recorded in the Family Tree.
What are the objects in the family tree?

What should be included in a family tree chart?
Most family tree charts include a box for each individual and each box is connected to the others to indicate relationships. In addition to an individual’s name, each box may include dates, birthplace, and other information, depending on the desired complexity of the family tree diagram.
