Join Geoff as he consults with DNA expert Diahan Southard to determine if mtDNA and/or XDNA can help him learn more about his 4X great grandmother.
In this engaging and insightful webinar hosted by Legacy Family Tree, genetic genealogy expert Diahan Southard joins Geoff Rasmussen in a live case study to explore whether mitochondrial DNA (mtDNA) and XDNA can break through one of Geoff’s long-standing genealogical brick walls. Focusing on his fourth great-grandmother, Sophronia “Fanny” Kintz, Geoff combines traditional genealogical research with modern DNA analysis. The result is a compelling journey into how DNA testing—particularly mtDNA—can contribute powerful clues to longstanding family mysteries.
Through real-time demonstrations, Diahan unpacks the nuances of various DNA testing methods, explains the inheritance patterns of mitochondrial and XDNA, and guides viewers through practical techniques for leveraging those results. This session stands out for its interactive approach, offering a rare look at a real genealogist’s evolving discovery as new evidence unfolds.

That was a very interesting session, thank you both, Diahan and Geoff. I have used filters etc for ages but I liked how you used filters within filters. Fingers crossed it helps me find my maternal grandfather’s father. I know his name through RCE record on Scotlandspeople, found two families same name, both ‘father’s’ went to USA at a similar timeframe. Have created both trees, now trying to find out which one via DNA. Thanks again.
I had wanted to watch this program when it was first presented and life got in the way. I have now watched the recording. This was a great program. I did my mT DNA back when that was the only option for women. I did upgrade to the full sequence last year. The problem was that I never really know how to use it. Thank you so very much for the techniques that you shared. Because of this, I believe that I have found a second cousin. Now, on to more reseach to prove what I found. Again, THANK YOU SO MUCH.
Geoff has the best genealogy karma of all! Great webinar. Thanks.
This webinar was SOOO great! Thank you both and Diahan it kind of took away the mental block I have about trying to understand DNA research. It was so amazing for Geoff to actually find and prove his 4th great grandmother! Wow!! Wow !!! I can only hope that I will find and prove my 2 x great grandfather/grandmother in time. Thank you again.
OMG! This presentation was informative, instructive and inspiring. I could feel Geoff’s sense of being overwhelmed and grateful. I am happy to learn HOW, if all the stars align, you can get your family back using mtDNA. Thank you both!
Excellent webinar!! The best that I have seen in ages.
Thanks for another wonderful insightful and helpful learning session.
Great job! Really informative.
