About us
We are actively seeking surname Clay participants for testing and the Clay Family Society is not opposed to helping new testers with payment and existing testers to upgrade their yDNA test to the Big-Y.
It is now recommended that all Clay yDNA project members upgrade test below y67 markers to y111 or Big-Y y700 markers.
We have initiated a plan to include only y67 and above marker tests in this project.
Latest subgroup to be created: 4.1b. Germany - Johan Klee (1712 - 1753)
