The Why of Y!

Curious about your paternal line? Wondering about the "why" of the "Y" DNA? This course is for you! The course is well laid out and will challenge what you think you know and understand about how Y DNA is inherited and passed down from father to son. There will be plenty you don't understand at first but the good news is that all materials will be available to you to review. Diahan and her team are very responsible to questions and comments. There are also videos on YouTube. I look forward to taking another class from Diahan in the future!

YDNA for Geneaolgy

This course was very clearly and well presented and coaches are available to answer questions. I did not learn my not too distant paternal "roots" as was hoped, but that is because we don't have any good matches (yet). I know I will be going through the lessons again (and again) once I have upgraded my brother's test from 111 to BigY-700 and gotten the results from my cousin's BigY-700 test. I am also hoping to start a surname project of our own once I am able to contact more distant relatives who have autosomal DNA results about taking a BigY-700 as well. Thank you to Your DNA Guide for providing the lessons for as long as the platform is viable. It will be very helpful as I move forward.

Excellent information

I learned how to follow up on a YDNA match that has no surname matches. I'll be looking at the videos often.

YDNA Course

I enjoyed this class and learning more about the research process with YDNA. All the training tools and assistance during the three weeks of training it has helped me find new information about my ancestors.
I was able to ask questions and the answers to increase my research.

Double Whammy

My paternal great grandfather and one of my maternal great-great grandfathers were brick walls. The former came out of nowhere and left very little information about himself. The latter was born four years before the couple who raised him were married.
My brother did a YDNA test and I paid to upgrade it to BigY-700. A maternal cousin also did the BigY-700 test. Both gave me access to their results.
And this course taught me how to understand those results.
In both cases, I found out what surnames to search under because neither one matched what we had from the records. Using autosomal DNA matches, I believe I have found people who may be the cousins I need to locate our biological ancestors.
And it wouldn't have happened without Diahan's great instruction.
There are very few easy answers in DNA research, but when you learn from someone who knows the science, you avoid so many pitfalls, rabbit holes, distractions, and confusions.
I'm very glad I signed up for this course and I look forward to checking the YDNA results every so often, and using autosomal DNA matches, and doing genealogy with all of this new information to break down these two brick walls.
