Generational trauma is unresolved trauma and shame genetically inherited from your mother or father through epigenetic inheritance. It surfaces as disempowering feelings and behaviours that make no sense in the context of the life of the person experiencing them.

Sources of generational trauma

Anything traumatic or shameful is a potential source of generational trauma, including (but not limited to):

  • Abuse (physical, emotional or sexual)
  • Sexual impropriety
  • Financial/social scandals
  • Abandonment
  • Unexpressed grief
  • Wartime ‘shell shock’
  • Neglect

Generational trauma can also surface as patterns of destructive behaviour, e.g. a family that has recurring marriage breakdowns due to infidelity over multiple generations. Because of the invisible nature of the underlying condition, and that cause and effect are spread over generations, it’s difficult to identify and resolve.

Epigenetic inheritance

Generational trauma replicates through a mechanism known as epigenetic inheritance. It’s effectively an inherited form of Post-Traumatic Stress Disorder (PTSD).

Epigenetic inheritance has been proven in the laboratory. Mice were given ample food and behaved normally. The food was then reduced to a minimum and the mice became aggressive and anxious.

The food supply was then reinstated. The mice’s aggressive behaviour did not change. A new generation of mice was bred from these aggressive mice. The offspring were given unlimited food from birth, yet retained their parents’ aggressive conditioning.

Generational sin

While the understanding of the mechanics of epigenetic inheritance is fairly recent, generational trauma has long been recognised. The Christian church refers to it as ‘generational sin’ or ‘generational curses’. It is referenced on several occasions in the Bible (e.g. Exodus 20:4-6, Jeremiah 31:29 and John 9:1-3).

Deuteronomy 23:2 is an example of intergenerational shaming for sexual impropriety: “No one born outside a legal marriage, or any of their descendants for ten generations, can fully belong to the Lord’s people.”

Biblical shaming of sexual behaviour has cascaded shame from one generation to the next: “I tell you not to divorce your wife unless she has committed some terrible sexual sin.” (Matthew 5:32)

Cannot process

Generational trauma is created when a traumatic event occurs that the person experiencing it cannot process. I’ve written about this in more detail in The mechanics of emotional pain. The trauma is simply an accumulation or backlog of experience that was too painful to be processed—i.e. fully felt—and released when it happened.

When animals are traumatised, they systematically shake their bodies to release the trauma. Humans go into shock, denial and emotional shutdown. The unresolved trauma embeds in their DNA and is then handed down in diluted form to their children.

What is the unconscious?

Here it becomes part of the child’s unconscious. This is a pool of traumas from their current life as well as inherited trauma from recent and distant ancestors (ancestral trauma). Ultimately, all traumas are downstream from the core separation at the heart of our being, the mother wound.

Despite having no direct experience of the traumatic event, the child is affected by it in a similar way to PTSD. Because of the disconnection between the source of the trauma in one generation and its expression in a later generation, generational trauma is hard to identify.

Arrested development

Generational trauma may take a relatively low-grade form or it can have a very significant impact. This can result in instances of arrested development (also known as ‘developmental disorder’), where crucial developmental tasks in the child’s life don’t unfold correctly.

The Medical Dictionary defines ‘developmental tasks’ as:

Fundamental achievements that must be accomplished at each stage of life, arising at or near critical stages in the maturation of an individual; successful attainment leads to a healthy self-image and success with later tasks. Failure to achieve developmental tasks at one stage leads to unhappiness in the individual, disapproval of society, and difficulty in accomplishing later developmental tasks.

This happened in my own case when my grandmother had an affair in 1932. She was evicted from the family. My mother was deeply traumatised that her mother preferred an affair to raising her daughter. My mother was unable to process the double-whammy of abandonment and sexual shame. She was emotionally crippled for life. I inherited her unprocessed feelings and had to process them as part of my own healing journey.

Not only did I have to deal with my mother’s unprocessed shame and feelings of abandonment, my mother-child development process was significantly affected right from birth. This affected my ability to communicate, connect with others, and to nurture both myself and other aspects of my life (e.g. family, career, creations).

Further reading

In The emotional cost of generational trauma I go into greater depth about its impact.

Suzannah Lessard’s The Architect of Desire is a classic study of generational trauma. Lessard’s great-grandfather Stanford White was a leading architect during the American ‘gilded age’ of the late 19th century. He was also a serial sexual abuser whose murder caused a national scandal.

Stanford White’s sexually motivated murder cascaded shame and sexual abuse across several generations of Lessard’s family, a trauma that she unpicks in her harrowing and courageous account.

Paula Uruburu’s American Eve – Evelyn Nesbit, Stanford White and the birth of the ‘it’ girl tells the story from the perspective of Evelyn Nesbit, the beautiful young ingénue at the heart of the Stanford White scandal.

Healing generational trauma

How do you identify family skeletons, i.e. generational trauma, in your family?

Your family tree is the obvious place to start—as are the emotional symptoms you’re observing, in your life or those of family members, which make you question if you’re dealing with generational trauma.

A lot of this is basic genealogical research advice—with one significant exception. The information you seek is often noticeable only by its absence.

You’re looking for ‘skeletons in closets’: sex scandals, financial ruin, sudden deaths, illegitimate children—all the things the chroniclers of your family didn’t want to record for posterity.

Like a detective at a murder scene, you’re looking for disturbances in the ‘loam’ of your family history. And, as they say, the dead don’t talk.
