About us

January 8, 2009. The Glenn, Glynn, Glen Surname DNA Project has been working since 2003 to establish relationships between the various Glenn families worldwide. As a supplement to traditional genealogical research, this Y-DNA study will help identify Glenn families who share a common male ancestor. My pc@cjglenn... email address gets filtered. If you have problems getting a hold of me, email me at and include (exactly) the words "Regarding Glenn Group" in the subject line. This will bypass spam filters and get your email to me.

There are many apparently unrelated families that use the Glenn surname. Some Glenns are of Irish ancestry, some are French, and some are English. Also, some clans, like mine for example, may have taken the Glenn name based on a group they felt an affinity to--even if they were not related to all of the people in that group. Genetic DNA testing is not a magic wand. When you find a close match, it gives you the potential to collaborate with another researcher of your surname to determine a connection--which can lead to a breakthrough. A perfect match with someone of the same surname on 25 or 27 markers almost always indicates a direct connection -- but that connection could still be beyond the paper trail that exists -- especially with the Irish Glynns (most Irish records were lost in a 1921 Dublin fire). That said, finding a perfect match with someone in Ireland is my long term goal ... one I am still waiting for ... but every new member creates potential.

Have you reached a brick wall in your Glenn research, and don't know where to search next? Do you have hunches or theories about relationships, but lack the paper documentation to back them up? Is your Glenn ancestor related to one of the many Glenn families being researched by others? With advances in genetic testing, genealogists now have another tool to aid us in our family history endeavors. The Glenn Surname DNA Project was organized to determine whether there are genetic links between the various Glenn families in the U.S.A. and throughout the world. It can also serve to validate research within established lines, and to prove or disprove relationship theories when no documentation has been found through traditional research.

If you are researching a Glenn family, we invite you to participate in our study! The success of this project depends on the number of participants, so please pass this information along to other Glenn researchers!
How does it work? The Glenn DNA Project is a study of the Y-Chromosome DNA, which is passed from father to son unchanged, except for occasional mutations. The test provides you with a genetic fingerprint consisting of 12 or 25 numbers, which will be compared with the results of other participants in the study. If two people have a match, that means they have a common male ancestor somewhere up the line. The test won't tell you specifically who that ancestor was, but it can narrow down a time frame of when the most recent common ancestor lived.

We have chosen Family Tree DNA of Houston, Texas as our testing company. They are leaders in their field and are associated with Dr. Michael Hammer, Ph.D., Geneticist, associate research scientist in the Division of Biotechnology at the University of Arizona. The test involves the collection of cells by a painless swabbing of the inside of your cheek. The laboratory then analyzes the sample and prepares the results for comparison with other participants in the study. For more information about the test and Family Tree DNA, refer to the links at left.

Who can Participate? Because only males carry a Y-chromosome, participants must be males with the GLENN surname or direct male bloodline. But that doesn't eliminate females, or males with another surname, from becoming involved. You can ask any male relative (father, brother, uncle, distant cousin) with the Glenn surname to represent your family line, as long you both descend from a common Glenn ancestor.

Group Administrator Please email Christopher for comments or questions about the Glenn DNA project. Special thanks to Jeanie for setting up much of this web page. Jeanie, we have been unable to get in touch with you. We hope you are well, please email us when you log back in.
