DNA Special Interest Group

The Anne Arundel Genealogical Society’s DNA Special Interest Group (SIG) is a members-only resource for anyone curious about using DNA in family history research. Moderated by Kathy Korin and Tom McCarriar, the group welcomes AAGS members at every level—from beginners to seasoned researchers. Together, we explore how genetic evidence can enhance traditional genealogy and help members apply DNA tools and techniques to their own research questions.
