Re: Coryell Genetic Genealogy Study
We're using Y-DNA testing in combination with traditional paper-based documentation to learn more about the Coryell family. We're learning a lot.
Three direct descendants of Abraham have completed Y-DNA testing at the 37-marker level. Two claim descendancy from David Coryell and one claims descendancy from Emanuel. Comparison of the results shows matches of 35/37, 34/37, and 33/37. According to genetic genealogists, that supports the standard Coryell genealogy that says David and Emanuel Coryell were brothers. Furthermore, the predicted haplogroup for all three is E1b1b1.
So, we are well on the way to answering our first two questions:
1. Do descendants of David, Emanuel, and Samuel Coryell really share a common ancestor as is asserted by Coryell genealogies?
2. If the answer to #1 is "yes," then what is the haplogroup of that common ancestor?
FYI, the genealogies of our three direct descendants start as follows:
David Coryell (1704-1779)
Abraham Coryell (1738-1828)
David Coriell (1704-1779)
Elias Coriell (1741-1820)
Emanuel Coryell (1707-1749)
George Coryell (1734-1818)
Results are posted online and are kept up-to-date. Search for "Correll DNA Project" and click on "Y-DNA Results." We are subgroups 1 and 2.
The Coryell study is part of the broader Correll group. I tried to establish a seperate Coryell Project, but the testing company wanted to keep us with the Corrells. Perhaps it is just as well, because we've already found a branch of Corrells that matches the Abraham Coryell descendants. We've also found a branch of Coryells that is not descended from Abraham. I expect such discoveries will continue.
Tim, we need at least two more participants who claim direct descendancy from Abraham:
1. A descendant of Samuel Coryell (d. 1760)
2. Another descendant of Emanuel Coryell (preferably from a line different than George)
