Using Genetic Genealogy to Break Down a Brick Wall - Part 1

In the first session of this series, we explore how Y-DNA and Big Y testing can help you tackle those tricky family history "brick walls." Using James McAllister, a Virginia pioneer, as an example, we cover the basics of how Y-DNA traces your direct paternal line, what haplogroups are, and how small changes in DNA (called SNPs) can tell us about our deep ancestors. This introduction lays the groundwork for using DNA to unlock hidden parts of your family tree.
