A genogram is a graphic diagram that represents a person's family structure across a minimum of three generations, using standardized symbols based on the work of Monica McGoldrick. Unlike a traditional family tree —which only records descent—, the genogram incorporates relevant clinical information: illnesses, emotional bonds, traumatic events, relational dynamics.
The canonical convention comes from the book *Genograms: Assessment and Treatment* (4th edition, W.W. Norton, 2020) by McGoldrick, Gerson, and Petry. It is the standard used in clinical psychology, family therapy, family medicine, and social work worldwide. Professional software like GenoPro implements it faithfully to the standard.
In Family Constellations, the genogram serves as a preliminary skeleton for the session: the client or the constellator draws the visible system to then explore the invisible dynamics. It is important to distinguish: the genogram is McGoldrick (scientific, closed standard); Constellations are Hellinger (they do not have their own closed graphic system, they use the genogram as a base + systemic reading on top).
For the Constelando website, the minimum three-generation genogram is the most powerful visual tool to show systemic dynamics: an abortion that retains its ordinal place, previous partners who belong, exclusions that are not erased.
Clinical example
Before a session, a client draws her genogram: three generations, symbols for each member, marriage and separation lines. In doing so, she discovers something she had never articulated: her mother was the fourth child, not the third —there was an abortion between the second and her—. That data changes the complete systemic reading.

Evidence and contemporary voices
The clinical genogram is a systematic assessment tool formally developed by Monica McGoldrick and Randy Gerson in the 1980s, consolidating itself as a standard instrument in systemic family therapy. Its validity has been documented in clinical research contexts by institutions such as the Center for Family Research at Georgetown University and the Ackerman Institute for the Family in New York. McGoldrick and Wohlsiedler (2016) demonstrated that the genogram facilitates the identification of transgenerational patterns of behavior, trauma, and family resources through the structured visualization of at least three generations. In the field of transgenerational trauma, researchers such as Yolanda Gampel (2000) and Françoise Davoine have used genograms to map transmissions of historical and psychic trauma in families affected by war conflicts and persecution. The methodology has been integrated into attachment assessment protocols (Hesse, 2008) and in studies on family resilience (Walsh, 2003). However, its application requires specific training in systemic reading and does not in itself constitute an independent diagnostic instrument, but rather a tool for collecting contextual information.

Notes and open debates
Although the genogram is widely accepted in systemic family therapy, there are documented methodological limitations: (1) its interpretation depends significantly on the therapist's clinical competence, which introduces variability in pattern reading; (2) the information collected is subject to memory biases and constructed family narratives, not necessarily verifiable facts; (3) specifically in the Hellingerian context, attributing current symptoms or behaviors to “exclusions” or “hidden loyalties” identified in the genogram lacks a scientifically demonstrated causal mechanism, differing from its use in conventional systemic family therapy where observational correlation is emphasized without transgenerational determinism.
