The Stiles Family of America and Affiliated Families, Inc. (SFA) established its Y-DNA Project in July 2007 to support genealogical research and help participants better understand their Stiles and Styles ancestry through DNA testing. The project combines traditional family history research with genetic evidence to identify relationships, confirm lineages, answer research questions, and explore the origins of Stiles family lines.

Our goal: To help the Stiles Family of America and individual researchers use DNA testing to confirm, correct, and expand Stiles genealogies.

Volunteer researchers work with both DNA results and historical records, drawing upon SFA's extensive collection of more than 370,000 individuals in its database as well as numerous paper records. Because many Stiles ancestors shared common given names such as William, John, Robert, Samuel, and James, DNA testing often provides valuable evidence for distinguishing between individuals and family branches.

The project welcomes participants from around the world, including the United States, Canada, England (United Kingdom), Scotland, Ireland, Australia, New Zealand, and beyond. We encourage participants to provide at least four generations of family information whenever possible to assist researchers in identifying connections and placing results within the broader Stiles family network. Those who do not yet know their lineage are also welcome, and project volunteers may be able to help research their family tree.
