From Secrets to Science: How DNA Testing is Rewriting Family Histories
What happens when the story you’ve been told about your life suddenly changes? For many, family history is a neat pedigree chart of names and dates. But as the world of genetic genealogy evolves, those charts are being challenged by the undeniable truth of science.
In this episode of the Legacy Tree Podcast, Sarah Stoddard, an advanced researcher at Legacy Tree Genealogists, sat down with Richard Hill, the founder of DNA Favorites and a pioneer in the field. Together, they explored the emotional rollercoaster of DNA discovery and how technology is turning “family secrets” into “family history.”
The Late-Discovery Adoptee: Richard Hill’s Journey
Richard Hill didn’t grow up knowing he was adopted. He discovered the truth accidentally at age 18, but it wasn't until 14 years later that he began a decades-long quest to find his biological roots.
At the time, traditional records only took him so far. It was Y-DNA testing that finally broke through his “brick wall,” allowing him to identify his birth father’s surname and eventually connect with biological siblings. Richard’s story, detailed in his book Finding Family: My Search for Roots and the Secrets in My DNA, serves as a roadmap for others navigating the complex waters of unknown parentage.
The Power of Combined Evidence
Sarah Stoddard highlights a critical transition in the industry: the move from traditional paper-trail research to genetic evidence. Sarah’s own interest was sparked by her father’s involvement in a Y-DNA project, which eventually disproved a long-held family belief about their 1600s Virginia ancestors.
She emphasizes that the most successful research today uses a “braided” approach:
- Traditional Records: Census data, birth certificates, and historical archives.
- Genetic Testing: Using Autosomal, Y-DNA, and Mitochondrial DNA to verify those records.
“We’ve gained more tools to understand the universe of our family history. It’s a lot like science; we are constantly learning and adjusting as new evidence arrives.”
— Sarah Stoddard.
Navigating the “DNA Surprise”
Both experts agree that DNA testing often reveals “Non-Paternal Events” (NPEs)—instances where the biological father is not the person listed on the birth certificate.
Richard shared his experience of “whiplash,” where early testing pointed to one man, only for later, more advanced autosomal testing to reveal that a different brother was actually his father. This underscores a vital tip for researchers: be open to new evidence. What was considered a “scandal” in 1940 is often viewed simply as “history” today.
3 Essential Tips for Genetic Genealogy Beginners
If you’re just starting your journey with a home DNA kit, Sarah and Richard suggest these best practices:
- Test at Multiple Sites: Different companies (Ancestry, MyHeritage, 23andMe) have different databases. Being in all of them increases your chances of finding a crucial match.
- Use the Shared cM Project: This tool helps you understand the statistical probability of your relationship to a match based on the amount of DNA you share.
- Be Diplomatic: When reaching out to a surprise match, don't lead with “I think we’re related because of a secret.” Start by mentioning you are a DNA match and would love to compare family trees to find the connection.
Preserving the Legacy
As testers age, the “custodianship” of DNA becomes vital. Sarah notes that as older generations pass away, their DNA results remain a permanent part of the database, acting as a bridge for future generations to find their way home.
Genetic genealogy isn't just about the science of A, C, G, and T; it’s about the human stories that connect us all across continents and centuries.
