Foundations in DNA 3 of 5: Understanding Autosomal DNA
Autosomal DNA (atDNA) is a powerful tool for genealogists, offering a window into your broader family tree. This lecture explores the science of atDNA inheritance, its strengths and limitations, and practical ways to apply it to your genealogical research. Discover how atDNA can help you identify unknown ancestors, connect with relatives, and solve family mysteries.

Foundations in DNA 2 of 5: Understanding and Using Y-DNA and mtDNA
Y-DNA and mtDNA have revolutionized genealogical research, breaking through barriers that once seemed insurmountable. This session dives into the unique inheritance patterns of Y-DNA and mtDNA, showing how these tests trace ancient ancestry and identify relationships both close and distant. Gain insights into their application for solving lineage mysteries and uncovering ancestral connections.

A very basic introduction to DNA and how it can be used in combination with traditional genealogical research. Together we will examine the answers to questions like: "why should you test your DNA?" and "how do I get started with DNA?"

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.

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.
