Yes, Steve, again ... AND THIS IS NOT A NEGATIVE CRITICISM OF YOU KEEP THAT IN MIND ... so long as you don't leap into the air shouting at me ... again ... LOL ... Okay?
There's no place for DNA test results in genealogy unless there is a lineage, a family tree -- in short the genealogy of a particular individual -- themselves, their parents, grandparents and etc as far back into time as the records in various archives will permit
JUST strictly from the WT position without the profiles, one connecting parents and child(ren) DNA test results posted have not value. And we have seen a few cases like this come through G2G where they did their own profile and posted their DNA and ... nothing happened, why not? That's often because they have no other profiles created.
The lineage can't be verified without test results. Now, you CAN get along without having the tests and tracking the Y-DNA and mtDNA. You cannot be certain on the other hand that there is not a NPE floating round in there
We see this often enough in G2G forum, descended from a notable or royal but ... they do not have the DNA to confirm it. Or they do have the DNA results and now discover Uncle Max, their grandfather's illegitimate son, is also THEIR father or half-brother or whatever. (Always seems to be a shocker)
I did not and do not speak to the "outside" uses and value of DNA testing, meaning I am speaking only from the WT point
