One-stop shop for learning about DNA testing, whether you’re a beginner or an expert on DNA. Topics include Y-DNA, mt-DNA, Autosomal DNA, third-party tools, methodology, organization, and much more.
The first cousin-matching autosomal DNA tests became available in 2009. Sales have exploded in the last few years and over 30 million people have now tested. However, the currently available tests still have many limitations. It is important to consider these uncertainties when incorporating DNA evidence into genealogical research. As…

Shared matching is an essential strategy for tackling genealogical puzzles and breaking through brick walls. In this lecture, we’ll demonstrate how to use shared matches effectively, focusing on strategies to solve mysteries related to ancestors from the 1900s, 1800s, and beyond. Learn how this technique can reveal hidden connections and strengthen your research.

Our DNA matches can’t really help us if we don’t know who they are. But we also need to ask ourselves what the match is telling us and what evidence it can provide for our genealogical research.

Genealogists who overlook or underutilize the MyHeritage DNA test miss out on many great tools. Using examples from his personal account, Richard will demonstrate these features and show how they can be used productively by genealogists, adoptees, and anyone curious about their family history or ethnic background.

Foundations in DNA 5 of 5: Understanding Ethnicity Estimates
Wed, October 1 2025: 18:00 UTC
Ethnicity estimates can provide a fascinating glimpse into your ancestral origins, but understanding their scope and limitations is key. This session examines how testing companies generate ethnicity estimates, what they reveal, and how they can be used in genealogical research. Discover how to interpret these estimates in the context of your family history and integrate them with other tools for a more complete picture of your heritage.

Geoff’s Got ANOTHER Brick Wall! What Can DNA Do for It?
Wed, October 8 2025: 18:00 UTC
Geoff Rasmussen has never used DNA on his most famous case: Eleanor Huffman (Asa Clark Brown’s wife). It’s a SERIOUS brick wall. BUT: his grandmother AND her sister have taken DNA tests, and Eleanor is their 2x great grandfather. What light can their DNA test results shed? DNA expert Diahan Southard gives him advice you may be able to apply to your own brick wall, too.

Unlocking the X-Factor: Key Tips for Using X-DNA in Your Research
Wed, December 3 2025: 19:00 UTC
X-chromosome DNA is often one of the hidden gems of the genetic genealogy world especially when used in conjunction with autosomal DNA. This webinar will present an overview of the unique inheritance patterns of X-DNA and set out how and why X-DNA matching differs from atDNA matching. Michelle will guide you through the advantages of utilizing X-chromosome data and demonstrate how to use it to effectively narrow down and identify connections with your DNA matches. She will also cover which companies provide access to X-DNA data, include an array of tips on how to set yourself up to succeed with X-DNA and provide genuine case study examples that show what can be achieved when you harness this powerful type of DNA.

Scattered Leaves: Reconnecting family branches with DNA
Thu, December 11 2025: 1:00 UTC
When our families scattered across the globe, they often left close family behind. The family connections were lost over the subsequent generations. Now through family history research and DNA we are reconnecting with the branches of our family tree as shown in these case studies.
