FTDNA had them as "predicted M269," which is not much help of course, but their STRs contained the M222 indicators. But since they were on the fringes of my Byrne/Burns/Beirne NWI cluster, and since some accounts had Niall, Brion, and Fiachra living in Roscommon, I wondered if they could be pre-M222. After ordering the DF23 tests, I realized that I should have started with M222 tests, then worked upwards if that test turned out negative. So I still do not know whether they are DF23+/M222+ or DF23+/M222-. I looked at one of their haplotypes. I forget which sample. But he had a Nial icon. It's a pretty safe assumption he will be M222+. FTDNA thinks so anyway. Susan just sent me her SNP results. It was L21+ and M222+. Apparently they are not yet including DF23 in their basic haplogroup deed clade testing. John
