DNA Research Special Interest Groups

Join Our Email List-Meeting Notices & Zoom Links
DNA results alone can't solve your research problems, but when combined with traditional research, they can:
  • Verify traditional research
  • Identify potential ancestors to fill gaps in your family tree
  • Suggest relationships between individuals
Genealogy Friends offers two groups that can help you learn how to incorporate DNA into your genealogy research.
