Thanks for bringing further clarity to our haplogroup. Perhaps
another refinement would be a micro-clade Kenneth has denominated C21219,
which includes Walls #80999, Anthony #18187, Graves #2238, and Stewart #145573
in our project group. The key markers are as follows: DYS388=12,
YCII=19-19, DYF406S1=9, DYS461=11. Altogether, this group includes
twenty-three Y-DNA matches: ANTHONY (3), GRAVES (9), WALLS (3), STEPHENS
(3), YAW (2), STEWART (2), and one who has tested with ancestry.com.
