About this webinar

To introduce the concept of haplogroups to beginners, explaining what they are, how they are inherited, and what they reveal about ancient ancestry and human migration patterns. The session aims to demystify the complex terminology and provide practical insights into how haplogroups can be used in genetic genealogy and guide participants to find their own haplogroup.

About the speaker

I’m a New Zealander with English, Scottish and Irish ancestry. Many of my family were New Zealand pioneers. At the beginning of 2015 I decided to take an Ancestry DNA test. Once I got the results I spent all my spare time immersing myself in

Key points and insights

In the engaging webinar “Demystifying Haplogroups” presented by Donna Rutherford, genealogists and DNA enthusiasts were introduced to the foundational concepts and applications of haplogroups in genetic genealogy. With clarity and enthusiasm, Rutherford explained how haplogroups, inherited through either the patrilineal (Y-DNA) or matrilineal (mtDNA) lines, offer insights into ancient human migration patterns and deep ancestral origins. Whether attendees were beginners or seasoned researchers, the session provided valuable tools for understanding what haplogroups are, how to discover them, and how they can be used in the context of family history.

Key Takeaways from the Webinar:

  • Haplogroups as Genetic Surnames: Rutherford emphasized that haplogroups function as genetic family names, helping to trace deep ancestral lines. Y-DNA haplogroups are passed from father to son and reveal patrilineal ancestry, while mitochondrial DNA haplogroups are inherited from mothers and apply to both sons and daughters, illuminating the maternal line.
  • Types and Testing Levels Matter: The webinar differentiated between high-level haplogroups provided by autosomal tests (e.g., 23andMe or Living DNA) and more precise, lineage-specific results derived from comprehensive Y-DNA or mtDNA tests at Family Tree DNA. These advanced tests enable genealogists to trace their family’s genetic lineages back thousands of years and contribute to building detailed haplogroup trees.
  • Real-World Case Studies Illuminate Research Value: Through personal examples—including discoveries from her Rutherford surname project and the unexpected haplogroup results of her son—Rutherford illustrated how haplogroups can uncover migration patterns, confirm family origins, and even challenge assumptions about ancestral backgrounds.

For those interested in enriching their genealogical toolkit, viewing the full webinar is highly recommended. It provides step-by-step explanations, visual aids, and case studies that demonstrate how haplogroups can serve as a powerful complement to traditional family history research.

Finally, genealogists are encouraged to explore the extensive resources included in the webinar’s 59-page syllabus. This comprehensive guide contains the full slide deck, useful diagrams, reference links, and actionable tips to support both new and experienced researchers in applying haplogroup data to their own lineage exploration.

    Very interesting – I know a little about haplogroups, but it was great to dip a toe in a little further.

    Donna provided an excellent of DNA basics and brought me up to date with the various DNA testing organizations, especially FamilyTreeDNA where I have done most of my testing. An added bonus for me is that I am also a descendant of the Rutherford Family and I will be contacting Donna soon.

    Donna did a wonderful job of explaining Haplogroups and how they came about. I enjoyed her case studies about how she is trying to find where in Scotland her ancestors originated. Thanks for the wonderful syllabus, too.
