Genetic Genealogist
A trained expert who uses DNA and records to solve family mysteries, often helping adoptees or missing persons find biological relatives.

A genetic genealogist is a trained professional who uses DNA analysis and traditional genealogical records to reconstruct family histories and identify biological relatives. The field combines forensic science with historical research, often applied in adoption cases, missing person investigations, and ancestry verification. It differs from casual hobby genealogy by requiring rigorous methodology and validated genetic markers.
What this means in real life
When a woman takes a DNA test and discovers an unexpected half-sibling, a genetic genealogist can analyze the shared DNA segments, compare them to databases, and help trace their common parent by examining family trees and historical records.
What it isn’t
Not a geneticist or medical doctor—they don't diagnose diseases or study inherited conditions. They focus on ancestry and family connections, not health or genetic mutations.
Commonly misused online
Often conflated with DNA testing companies themselves; people say 'I used a genetic genealogist' when they mean they took a commercial DNA test. The genealogist is the expert who *interprets* results, not the lab that runs them.
