In the standard genogram, a couple's children hang from a **horizontal sibling line** that branches off the descending generational line. McGoldrick's convention is strict: the visual order goes from left (oldest) to right (youngest). This position is not merely decorative: it encodes the ordinal place within the system.
The ordinal place matters clinically. The firstborn carries different roles than the middle child or the youngest. Changing the visual order when drawing the genogram—"I'll put the male child first even if he was born second"—already distorts the systemic reading.
Here enters one of the most striking divergences from the clinical system: in Hellinger, **unborn siblings also occupy their place** in the horizontal line. If there was an abortion before the first live child, that first live child is not "the first": they are the second. This rule, called the *ordinal place of the lost child*, has its own entry in the glossary due to its clinical weight.
Clinical example
A woman grows up feeling "responsible for everything" even though she is an only child. When reconstructing the genogram with her mother, she discovers that there were two abortions before her. In the sibling line, she is the third. This explains the weight of the two empty places she unknowingly carried.

Evidence and contemporary voices
The concept of 'sibling line and birth order' is part of the 'Orders of Love' proposed by Bert Hellinger within the framework of Family Constellations, representing the temporal hierarchy in which siblings occupy sequential positions from oldest to youngest, including everyone regardless of their vitality. In empirical family systemic psychology, research on sibling dynamics and birth order focuses on observable effects such as the 'firstborn syndrome' (Sulloway, 1996), with studies in journals like Journal of Family Psychology analyzing impacts on personality and academic achievement using longitudinal samples (Paulhus et al., 1999). Institutions such as the University of Cambridge have explored correlations between birth position and traits such as responsibility or rebelliousness, using meta-analyses of data from thousands of families (Sulloway, 2010). However, there is no rigorous clinical evidence that validates Hellinger's literal symbolic representation in therapeutic contexts, limiting its use to experimentally unvalidated practices.

Open Notes and Debates
Family Constellations, including the symbolic use of the sibling line, lack empirical support in peer-reviewed literature; systematic reviews conclude an absence of efficacy and safety in mental disorders (Stöckigt et al., 2019), classifying them as pseudotherapy with risks of suggestion and false memories (PSIF Foundation, 2023). Methodological critiques highlight the unfalsifiability of premises and derivation from non-scientific models such as morphic resonance.

Clinical Genogram
A standardized family diagram that maps at least three generations using universal symbols (McGoldrick). The visual basis of systemic work.
See entryOrdinal Place of the Lost Child (Hellinger's Rule)
In the systemic system, a deceased sibling —including miscarriages and premature deaths— retains their ordinal place. If there was a miscarriage before the first living child, the first living child is "the second."
See entryAbortion in the Genogram — Conventions
McGoldrick: small filled triangle + cross (spontaneous) or triangle + horizontal line (induced). In Hellinger's reading: sometimes a darkened circle. The divergence is deliberate and clinically significant.
See entryParental Child
A child who assumes the emotional role of an adult —caring for their parents, mediating between them, containing their sadness— thereby breaking the systemic order.
