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.
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.
