Family Structure Genogram Examples

Family structure has evolved well beyond the nuclear model of two married biological parents and their children, and genogram notation has had to evolve with it. These examples show how to accurately diagram blended families with step-parents and half-siblings, same-sex parents using donor conception or surrogacy, adoptive and foster families with both biological and legal relationship lines, grandparents serving as primary caregivers, polyamorous family configurations, and transnational families separated by immigration. Each diagram demonstrates how to represent non-traditional connections using standard genogram notation so that any clinician reading the chart can immediately understand the family system without ambiguity.

Getting family structure right on a genogram is foundational work. If the structural diagram is inaccurate, every clinical layer built on top of it, whether emotional relationships, medical history, or behavioral patterns, will be misleading. Social workers conducting home studies for adoption or foster care rely on precise structural genograms as part of their assessment documentation. Family therapists working with blended families need to map which children belong to which partnership before they can begin addressing loyalty conflicts or boundary issues. The examples here give you clear, reusable models for the family configurations you will encounter most often in contemporary practice.
