Hi Ann,

I'm sorry but I simply cannot recall what values were included along
with the prediction of Q. I sat on that prediction for awhile as we
collected more Y-STR results to demonstrate that the group of Reddicks
from Georgia were in fact related. Only after we had collected some 37
marker results showing who was and who wasn't related did I decide to
have the SNP test performed. My personal results page has changed
several times as the Y-STR upgrades came through and I just don't recall
the details regarding the Q prediction. I simply recall my puzzlement
over the Q prediction. Here are my first twelve markers, upon which
that initial prediction of Q was made.

19 Reddick *R1b* 14 24 14 10 14 15 12 12 13 13 13 29

After FTDNA took those eight or so months to report that I'm not Q and
report that I am R1b, then Ethnoancestry also reported that I'm not Q
and that I am R1b1c.
