Abstract: A modular family tree doll system has a modular tree formed of a base member, modular trunk sections that snap-fit together, and modular branches that fit to one another and to the trunk sections. Dolls that represent progenitors of either gender back through several generations can be placed in doll swings or treehouses that are suspended from the branches of the tree. Flags can indicate the country of origin for the person that the doll represents, and the doll swings or treehouses, and cushions on the fixed swings or treehouses can be color coded to indicate blood lines. The system can be free standing or can be suspended on a wall, and can be expanded as more is learned about the ancestors.
