The DNA Study Group normally meets monthly on the last Monday at 6 pm MT. Due to the COVID-19 pandemic, these meetings are being held via Zoom video conferencing. You need to submit your email address to the DNA Coordinator to be included in Zoom invitations.

Meetings normally include a presentation and about 30 to 60 minutes of discussion regarding recent member successes, upcoming events of interest and assistance requests. Presentations usually focus on tips for conducting DNA research, including DNA web sites, and other research sources.


The DNA Study Group will be doing a book study in 2021 using: Genetic Genealogy in Practice, by Blaine T. Bettinger and Debbie Parker Wayne.

“Genetic Genealogy in Practice, the first workbook on genetic genealogy, the book provides family historians and genealogists who have just begun to explore genetic genealogy practical, easy to understand information that they can apply to their research. Readers learn the basic concepts of genetic genealogy. They then build on that knowledge as they study the testing, analysis, and application of Y-DNA, X-DNA, mitochondrial DNA (mtDNA), and autosomal DNA (atDNA) to reach and support genealogical conclusions. Each chapter includes exercises with answer keys for hands-on practice. 2016 208 pp. Paperback National Genealogical Society”

This book is available directly from the NGS. The NGS member price is $24.76 plus tax and shipping. The book is also available from Amazon for $36.00 plus $3.99 shipping or $9.99 on Kindle. Note: Please read the reviews on Amazon before ordering the Kindle version.

Everyone needs to have access to the book so they can study the chapter and work through the exercises before to prepare for each study group meeting. The study group will review the key material from the scheduled chapter and discuss the exercises each meeting.

This book includes nine chapters and we will cover one chapter each month. Each member should read the chapter and work through the Exercises before the meeting. Members will take turns leading the discussion at the monthly meetings.
