Symbology and genogram

Sibling line and birth order

Horizontal line from which children hang in birth order, from oldest (left) to youngest (right). All siblings—living, deceased, unborn—occupy their ordinal place.

Daniela Giraldo Systemic glossary

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.
