How does AncestryDNA discover the stories behind journeys?

 

DNA and Genetic Communities™ technology let us identify the connections that link AncestryDNA members into journeys. But DNA alone doesn’t tell us the story of why those connections came about or what their historical significance might be.

For that we add ancestral regions based on our reference panel, historical information from family trees linked to AncestryDNA tests, and historical research into the mix. Since journeys reflect fairly recent common ancestry, we look for patterns in region and tree data to help identify times, locations, or groups that members of journeys might have in common in their past.

We also use birth dates and places to identify common migration routes by looking at the differences between the birth locations of parents and children.

Once we know where these people lived, where they moved to, and when, we pass what we’ve learned on to historical researchers. Their job is to match the data with the history that explains it—to find the story that binds the members who share a journey together.
