Who should take this course?

Anyone who has identified (or strongly suspects) the presence of endogamy on a family tree and wants to learn straightforward DNA strategies for starting to untangle those intermingled genetic lines.

Not sure? Try using the Leeds method to separate your autosomal DNA matches into four distinct groups (which represent the four lineages of your grandparents). If you don’t have four distinct genetic groups, you may need this Course.

What topics will be covered?

  • Core Concepts: Get Ready for Endogamy!
    • Endogamy or multiple relationships–or both? How to tell
    • Setting an endogamy research goal: understanding what is likely achievable
    • Contacting your DNA matches
    • Targeted testing and targeted transferring
  • Straightforward Strategies across Autosomal DNA Testing Websites. There are nuances in the ways the various testing companies adjust (or not) for endogamy. Be sure you’re understanding what you’re working with at each testing company!
    • AncestryDNA
    • MyHeritage
    • 23andMe
    • Family Tree DNA
  • Organize, Visualize, and What to Do Next
    • Downloading and organizing your DNA match lists
    • Using Lucid Chart
    • YDNA, mtDNA and XDNA: How they can help you with endogamy
    • Next steps with Best Mystery Matches

Here’s what a recent participant in the Endogamy Course said about it:

Of all of the courses I have taken, this one [DNA and Endogamy] has provided me with the best value for my dollar, giving me a greater practical knowledge of how to process DNA cousin results and how to properly decipher and use the information. The whole course was a light bulb moment for me and I highly recommend it.

The strategies in the Endogamy & DNA Course shifted my whole work procedure and outlook on what good matches are and which are worth focusing on first. That was major for me.

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.

What do I get with this course? What is the format?

For the 3 weeks of interactive instructive, plan to spend about 2 hours per week on the Course. (Some people may work more quickly than others, and some may want to dive deeper. That part is up to you.) You’ll experience:

  • 3 weeks of self-paced, online instruction and practice using tools at your DNA testing companies, without the need for complicated segment analysis or spreadsheets
  • Weekly pre-recorded video tutorials, additional resources, homework, quizzes, polls, and a moderated discussion board
  • A final live Q&A session that will be recorded and made available with your Course materials
  • Full-length, professionally-designed workbook with classwork, homework, and research log (PDF format)
  • Homework that provides hands-on experience with real-life case studies
  • Enrollment in a class cohort that allows students to interact with one another at their preferred level

How can I best prepare for the Endogamy Course? Are there prerequisites?

By the time the course starts, you should have autosomal DNA test results in hand from 23andMe, Ancestry, MyHeritage, Family Tree DNA or Living DNA. (The cost and ordering of DNA testing itself is not included in the course.) These can be your own or someone else’s, as long as that person has endogamy on their family tree and you’ve got permission and login access.

During the 3 weeks of interactive instruction, you’ll need a reliable internet connection for streaming the video learning sessions and for additional learning on your own time. You’ll need access to your DNA test results on whatever testing site you’re using. There is no additional textbook to purchase: you’ll receive a unique Endogamy Workbook in PDF format and additional reference materials that support your learning.

While taking the DNA Skills Workshop is helpful and foundational for everyone working with autosomal DNA matches, it is not required for this Course. Come with a basic understanding of how autosomal DNA matching typically works, or patience and a desire to learn. (With your enrollment you will receive a coupon for 30% off a print copy of Your DNA Guide–the Book, which will help you get up to speed.)

I’m a reasonably advanced genetic genealogist with some experience working with endogamy. Is this Course too basic for me?

The Endogamy & DNA Course is a foundational course preparatory to the Advanced Endogamy DNA Skills Workshop (coming soon!). The organized approach presented in this course will provide insight into prioritizing DNA matches among the various testing companies.

Who is teaching?

This Course has been created by Your DNA Guide Diahan Southard, a globally-renowned genetic genealogy educator, to give you a progressive, confident and thorough learning experience. Throughout the Course, Diahan and her expert team will be checking your progress on the discussion boards.

Why enroll as soon as possible?
There’s great demand for learning DNA workarounds for endogamy. Endogamy can be a HUGE brick wall in your DNA analysis. Our unique multi-week, hands-on experience gives you straightforward strategies for FINALLY tackling endogamy more confidently and successfully–with DNA testing company tools that are ready at hand, and not too complicated. This Course has sold out every single session (once before we even started advertising it!) so it’s a good idea to enroll when there’s an open session.

Totally worth taking!

I am a descendant of many separate and very interwoven lines. Although I had figured out all my lines through records, I really needed help to figure out how to understand what this meant in terms of my DNA results.

The Endogamy and DNA course provided me with a much greater understanding of endogamy, its impacts on descendants and how to decipher my DNA results so I can get to the common ancestral couple. This is really not easy when you are a descendant from an endogamus people.

I am grateful I took this amazing course. It showed me how to decipher my many endogamous lines and additionally shone a light on my mysterious Y-DNA line I've been researching.

Of all of the courses I have taken, this one has provided me with the best value for my dollar, giving me a greater practicle knowledge of how to process DNA cousin results and how to properly decipher and use the information. The whole course was a light bulb moment for me and I highly recommend it.

Thank you Debbie! I'm so glad that you were able to make so much headway in your research!

Great Class

I took Diahan Southards' Endogamy DNA class after completing her DNA Skills Class earlier. I love her videos. The videos unique and explanations are easy to understand. That they are available to go back and rewatch is one of the many benefits of taking her classes. The homework for each lesson helps you wrap your head around the lessons she teaches. If I didn't understand the concept the first time, I could go back and redo it. Endogamy has been a problem in some of my research, and her class helped me identify new ways to unravel the puzzle. I would recommend that anyone with endogamy take her class. Diahan’s classes are the best!

Thanks you! We know it's so important to be able to go back and review the videos, that's why we made sure that all of our students could have access to watch those videos as many times as they need for as long as they need!

DNA assistance

The Irish ancestors lived in small locations for a long time. They use the same first names over and over. They tend to marry into the same families repeatedly. It's a mess! And so confusing to try and figure out. This course helped me decide which DNA matches would be most useful in making significant progress. DNA can be a difficult subject to master; the course and regular homework provided useful framework and focus. Topics are so well explained.

Thank you! So glad we could help you make progress with your matches!

N. Smith

Endogamy can show up in Quebec, Ireland, and other populations. Standard approaches proved ineffective for interpreting DNA results and planning documentary research. Diahan is masterful at breaking down this complex challenge into a systematic approach applicable at all the testing companies. The printed material, video, and discussion opportunities remain available even after the formal conclusion of the course. Helpful even for otherwise advanced researchers, this course offering on managing endogamy is unique among genealogy education options. I gained important skills and insight I use daily!

Thank you so much! We're so glad you continue to benefit from the information from our Course!

Easy to follow

The course was excellent.
It only helped my situation slightly as I have no known names.
I have reviewed the class notes which has helped..
It was well worth taking the time to complete this course.

So glad we could help you learn more! Thanks for leaving a review!
