For genealogists researching their Pennsylvania ancestry, AncestryDNA's genetic communities is essential.

AncestryDNA allows family historians to visualize familial connections beyond the basic DNA match list. This feature takes DNA testing to the next level, providing a window into the historical migrations and communities that shaped your ancestors' lives.

What Are Genetic Communities?

Genetic communities are groups of AncestryDNA members likely descended from a common ancestor in the same region and time period. These communities are identified through advanced DNA analysis, which can trace patterns of migration and settlement. For researchers, being linked to one or more of these communities can offer specific insights into their ancestors' journeys and lifestyles.

The Significance for Pennsylvania Genealogy

Pennsylvania, with its history of over 300 years of immigration, is home to numerous genetic communities identified by AncestryDNA.

From the early settlers of Central Pennsylvania to the Amish Country, Pennsylvania settlers, each community tells a story of migration and settlement that could be crucial to understanding your family's history. These genetic communities provide a context that goes beyond individual records, offering a glimpse into the collective lives of our ancestors.

AncestryDNA can confirm the accuracy of your existing family tree or suggest new directions for your research, especially if your family history intersects with multiple communities across Pennsylvania.

How to Use AncestryDNA Genetic Communities in Your Research

Review Your Genetic Community Assignments: Start by exploring the communities AncestryDNA has associated with your DNA. Each community comes with a detailed description, including the time period and common migration paths. Make sure to take screen shots for your records.
Cross-reference with Historical Records: Use the information about your genetic communities to guide your search for historical records. Look for documents that coincide with the locations and time periods of your assigned communities. If you have people of the same name in two different locations, the one with the genetic community that matches you is likely the correct ancestor.
Connect with Relatives within Communities: AncestryDNA allows you to see how you're connected to others within the same genetic community. Reaching out to these individuals can provide personal insights and additional information on shared ancestors. This is particularly helpful with brick wall research.
Keep an Eye on Updates: AncestryDNA continuously refines its genetic communities based on new data. Regularly check for updates to your DNA results, as new connections and communities may emerge, further enriching your understanding of your ancestry.
