Forensic Genealogy has revolutionized how we uncover identities, solve mysteries, and tell forgotten stories.
Neuropsychology, on the other hand, focuses on the brain’s relationship to behavior and cognitive function. At first glance, these two fields may seem worlds apart. Most people "cock" their heads with bewilderment, as to how these two displines intersect. But, in today’s world of interdisciplinary collaboration, their intersection is both natural and necessary.
By combining the precision of DNA science analyzed by forensic genealogists with the insights of brain science, we can approach forensic challenges with greater sensitivity, accuracy, and humanity. It's not just about solving puzzles; it's about doing so in a way that honors people and the families affected.
Where the Fields Meet
1. Memory and Identity:
The warning was strong and repeated about 5 times in the first meeting. I kept thinking, "Are you sure?" What's with the repeated warnings? They were VERY adamant and consistent in sharing:
Neuropsychology helps us understand how memories are formed, stored, and sometimes lost. In forensic genealogy, especially in cases of adoption, unknown parentage, or trauma, understanding the workings of memory can offer crucial context for missing or fragmented family histories.
Imagine Maria, a 52-year-old woman searching for her birth parents. DNA testing led us to several strong matches, but Maria had very few childhood memories, and almost none from her early years in foster care.
Neuropsychology teaches us that early trauma can disrupt memory formation. Therefore, gaps in her recollections are expected. In this case, forensic genealogy leaned heavily on genetic triangulation and archival research to reconstruct her family story, while neuropsychological insights could guide therapeutic approaches to support Maria’s emotional processing of her newly uncovered history.
The forensic genealogist builds the external factual story using DNA matches, documents, and genetic triangulation to reconstruct Maria’s biological family. The neuropsychologist interprets internal cognitive patterns (e.g., why Maria doesn’t remember things, or why recalling them now causes distress).
Usually, the next question asked is: How do these two disciplines interact as a team in Case 1?
They’re directly collaborating: the genealogist informs therapeutic work, and the neuropsychologist guides how genealogical findings are introduced. The neuropsychologist might request specific genealogical findings (like birth order, early caregivers, etc.) to fill in emotional gaps that help memory recovery or therapy.

Families often bury difficult histories.
Let's take James, a 30-year-old man, as an example. James came to us after finding a mysterious DNA match listed as "half-sibling." His family had never mentioned another child. Digging deeper, we found that during a particularly stressful time in James’ mother's life, a period marked by severe depression, she had placed a child for adoption.
The forensic genealogist confirmed the biological relationship and uncovered the adoption history through DNA analysis and records. Due to James' and his family's reaction when he reached out to the forensic genealogist (me), a neuropsychologist was engaged to support James' and his family's emotional reactions while the genealogist provided the verified facts.
As genealogists, we work with data. Of course, there are theories of how biases are formed, but we look at historical documents, cultural and community influences, and political and social impacts for a sketch of our ancestors' choices. Neuropsychologists, on the other hand, are experts at examining how cognitive biases form.
At a3Genealogy we do not work to identify "Jane Doe" or on cold cases. We are, however, familiar with neuropsychologists who have worked on these cases.
