Using genetic genealogy to reconnect families and answer long-standing questions.
DNA has transformed genealogy by providing another source of evidence alongside historical records. Throughout the Chagnon Family Project, DNA testing has confirmed family relationships, solved long-standing mysteries, identified unknown ancestors, and strengthened documented family connections.
Rather than replacing traditional genealogy, DNA works alongside historical research to create a more complete understanding of our family history.
This section explores how DNA has contributed to the Chagnon family story and demonstrates how modern genetic genealogy continues to expand what we know about our ancestors.
DNA and the Chagnon Family Tree
For generations, family history relied on photographs, documents, newspapers, and the memories passed down through relatives. Today, DNA testing has become another valuable source of evidence. Combined with traditional genealogy, it has helped confirm documented relationships, uncover previously unknown family connections, and answer questions that had remained unsolved for decades.
When DNA Changed the story
Behind every DNA match is a human story. Sometimes DNA confirms what family records have told us for generations. Other times, it reveals unexpected connections, uncovers long-hidden secrets, or answers questions that have remained unsolved for decades. These real-life investigations demonstrate how genetic genealogy has transformed our understanding of the Chagnon family and the lives connected to it.
One Branch, Two Sisters, and a Hidden Truth
For more than sixty years, Michael knew only that he had been adopted as an infant. His original birth records were sealed, leaving him with few clues about his biological family. Like many adoptees searching for answers, he turned to DNA testing in the hope that it would reveal the people and story he had spent a lifetime wondering about.
One exceptionally close DNA match quickly identified his biological father’s family. As the investigation continued, another branch of the family tree pointed toward the Chagnon family, where the search for his biological mother began.
At first, the records appeared to tell a straightforward story. But as DNA evidence was compared with historical records, timelines, and family relationships, a surprising discovery emerged. The woman everyone believed to be Michael’s biological mother was not the correct sister. The evidence pointed instead to another member of the same Chagnon family.
By carefully following both the DNA and the documentary evidence, the mystery was finally solved. Michael not only discovered the identities of both of his biological parents but also gained a deeper understanding of the Chagnon family branch to which he belongs.
This investigation is a reminder that DNA is most powerful when combined with traditional genealogical research. Together, they can answer questions that have remained hidden for generations and reconnect families with their true history.

The Name on the Birth Certificate Was Kent—
but the DNA Told Another Story
For most of her life, Abigail believed the name recorded on her birth certificate identified her biological father. It was the surname she had been given at birth and the family connection that appeared to explain where she belonged.
But when Abigail and members of her family took DNA tests, the results did not support the story recorded in the official documents.
Instead, her DNA matches pointed toward an entirely different family—one with connections to New York and Vermont. Finding the truth required much more than locating a single close match. Shared matches, family trees, census records, city directories, birth records, and carefully reconstructed timelines all became part of the investigation.
Several families appeared in the evidence, and more than one man initially seemed capable of being Abigail’s biological father. As each possibility was examined, some were eliminated while others became more compelling.
The investigation eventually led to a surprising conclusion about Abigail’s biological identity and revealed how a name could become part of an official record even when the genetic evidence told another story.
This case demonstrates how DNA can challenge long-held family beliefs—but also why DNA matches must be supported by documentary research, relationship analysis, and a carefully developed body of evidence.

A DNA Match That Changed Everything
DNA Continues the Story
Every new DNA test has the potential to answer questions that previous generations could never solve. As more descendants test and additional records become available, the Chagnon family story will continue to grow. Future discoveries may identify unknown relatives, reconnect lost family branches, and preserve an even more complete picture of our shared heritage.
