About this webinar

We never knew the birth parents of my 2nd great grandmother, Sena. Her mother died on the ship coming from Norway. Baby Sena was raised by another Norwegian family. This case study details how an X-DNA match led me to Baby Sena’s father—my 3rd great grandfather. This talk covers X-DNA inheritance patterns and how they can help you determine how you’re related to a match.

    Really helped me with understanding how inherited X chromosome DNA can be used to identify more relationships with matches. Mary’s comments about the availability of X-DNA from the different testing companies was particularly useful, have not heard those details before.

    This was a great new way for me to look at inheritance. I have seen the X DNA in both FTNDA & GedMatch but never really knew how to apply it. Thank you for this new insight. That was a great process you showed. I often go back and forth with Google and other searches in between the genealogy sites. It’s amazing how you can resolve something like that that easily.

    This was a great case study using X DNA. It was a bit difficult to follow a few things (e.g., the initial chart showing X inheritance because relationships were not quite clearly defined), but overall it was a great demonstration of how powerful it is to use X DNA in our genealogy.

    Very instructive case for using X-DNA in family history research

    I have had my DNA on GEDmatch for years and had absolutely no idea the magnitude of an X match. Mary explained how to use it wonderfully. I am glad I have a long weekend coming up so I can do some research.

    All of the information is this particular Webinar is very new to me and I did appreciate the introduction to this topic which has sparked my interest to learn more on the subject of DNA matches and Chromosome 23.
