As the maternal-paternal Genogram illustrates, just like a basic family tree, the family is represented in a hierarchy, with the parents above and any children of the couple listed below. You can add several generations to the Genogram. It should be noted here that Genogram symbols usually display the date of birth (and date of death if applicable) above the box and the individual's name underneath. In addition to this, the maternal-paternal Genogram will use different lines between members of a family tree to show different types of relationships. A solid line connecting two people horizontally indicates a marital relationship. A dashed line between two people indicates a non-marital, cohabitation relationship.
