Distinct enough from Historical trauma?
Indigenous mental health professionals, within the context of new research, use the term “Intergenerational trauma” (see the work of Cynthia Wesley-Esquimaux, Suzanne Stewart)
One initial question I have is, what is the work being cataloged that would provide literary warrant for the proposal? Is it one of the three examples cited here? The form “Transgenerational trauma” is only supported by Wikipedia here, so we would need other evidence to support the heading as currently worded.
