RLP 314: Banyan DNA and Double Cousin Relationships

The Research Like a Pro Genealogy Podcast

Diana and Nicole discuss BanyanDNA, a tool for analyzing complex family relationships in genetic genealogy. Leah Larkin introduced BanyanDNA in December 2023, highlighting its unique ability to identify unknown ancestors and alert users to discrepancies in family trees. Diana shares her experience with her own family tree, where her great-grandparents' siblings married each other, creating double cousins. She builds a tree using BanyanDNA, adding DNA matches from various test-takers, and finds the horizontal tree orientation helpful for visualizing relationships.

They explain that BanyanDNA allows adding DNA matches from any testing company and evaluates shared DNA to highlight discrepancies in documented relationships. The tool runs statistical simulations to compare expected DNA inheritance with actual data, providing insights into the accuracy of the family tree structure.

They discuss recent updates to BanyanDNA, including new calculation modes: VALIDATION and HYPOTHESES. Validation runs check if DNA matches support the documented tree, while hypotheses runs focus on the person of interest with potential unknown ancestors. These updates improve the speed and accuracy of BanyanDNA results.
