Hands down, Diahan Southard’s Endogamy & DNA online course is the best resource I have found for really learning how to dig into understanding endogamy, its impact on your autosomal DNA matches, and how to account for it when working those matches.
Endogamy can inflate the estimated relationship ranges that the genealogical DNA testing companies calculate for autosomal DNA matches. This webinar should provide you with a good free introduction to dealing with this challenge.
Are you new to DNA testing, just curious, or still on the fence? Perhaps you tested a while ago but need a refresher? Join me in beautiful Yorba Linda for the first Monday evening of the next two months.
I recently served as a faculty expert an article that the California State University system wrote about those popular direct-to-consumer DNA tests for family history.
What can DNA testing tell you about your ethnic origins? How can it be used to piece together your family history? Are those TV commercials all hype? How have anthropologists and historians used this type of DNA testing to solve historical mysteries? Can these tests reveal anything about your health?
Yesterday I launched my newest research guide, on using DNA for genealogical research — a focus of much of my own research time and dime this year. The research guide is by no means complete. I am still scrambling to add more material, and will continue to regularly update it. It is meant to be comprehensive, but not exhaustive. Includes a special getting started section for beginners.
