A visual mapping tool for demonstrating family links and history is available here. It's a graphical representation of a family tree that shows extensive information about individual ties. Marriages and divorces, reconstituted families, adoptions, strained relationships, family cohesion, and other events can all be visually depicted using genograms.
A genogram is a graphic representation of a family tree that shows extensive information about individual relationships. It goes beyond a standard family tree in that it allows the user to examine hereditary patterns as well as psychological aspects that influence relationships.
