You're right, Jim. L176- doesn't mean there wasn't a close association.
I'm perplexed by the CTS4179- that the R1a group shows for him because
it's not listed in Don's results. I have an email off to the admins and
have posted on the R1a1 facebook page for an explanation.
Here's a couple of things apart from specific markers to chew on...
We show only about a half dozen non-Cooley 12/12 matches. There are none
at 25 and above. The other R1a1a Cooleys (CF04) show 160 non-Cooley 12/12
matches and 55 matches to about 23/25. (I think they *might* be of the
Ferguson clan.) Not only are we rare among Cooleys, we're rare among R1a1a
Cooleys. I think that means that John came from a small population pool.
Could that mean that despite the large size of his family that he came
from a long line of few siblings? Could it mean that he came from a
region, say somewhere in the Scottish Highlands, that was particularly
isolated? Or perhaps he was of a more recent migration from Scotland,
perhaos even post Viking? That we have so many matching Cooleys only
proves that we've worked hard to get those. But the size of the ftdna
database is considerable. That we remain rare and *very* Cooley-centric (I
think I coined a new word!) might be significant.
