This presentation explains one of the research methodologies used to solve unknown parentage cases. This methodology focuses on the analysis of shared matches and presents several case studies illustrating how tools such as the Leeds method and the What Are the Odds? tool can be applied in the analysis.

A genetic network shows how a group of individuals who share DNA are related to each other. This presentation explains how to use the Leeds method, Scapple mind mapping software, and the Shared cM Project tool in a step-by-step process to build a genetic network in unknown parentage research.

This presentation describes how DNA was used to solve several unknown parentage cases, explains the analysis tools used, and identifies the lessons learned in each case.    

Endogamy is the practice of marrying within a limited community or group over many generations for cultural or religious reasons or due to geographic isolation. This presentation describes how to recognize endogamy in your family tree, explains its impact on evaluating DNA test results, and provides recommendations on how to deal with endogamy in your family research.     

This presentation provides step-by-step guidance on how to approach the analysis of DNA testing data and apply the results in your genealogical research. Topics covered include testing strategies, confirming relationships to family members tested, verifying the branches in your tree, identifying “surprise” cousins, and addressing brick walls in your distant ancestry.
