Dale, you are still not understanding some key pieces about how DNA works.
The patterns of repeats on STR markers can be used to rule out relationships, but not to prove relationships.
You've dismissed this key point many times in the past. From your explanations above, it seems you still do not accept mainstream DNA science.
Strictly speaking, you do not have a 23/25 DNA match to William Dudley 1609. If anything, you have a DNA match to a man who claims to descend from him, but that's not the same thing at all.
In fact, your match to him raises a number of awkward questions.
First, he doesn't belong to the right Dudley family. William Dudley 1609 is not known to belong to the Sutton Dudleys with whom you are trying to prove a relationship.
Second, you have no other close matches in the Sutton project, so you seem to be arguing that yours is the true Sutton Dudley DNA and the others are all from unrelated families.
Third, you have quite a few much closer matches than 23/25. At the 37 marker level you have ten 36/37 and 37/37 matches to the Cochrans and and several other surnames. At the 25 marker level you have 83 matches at the 24/25 level and hundreds of other matches at the 23/25 level -- to many, many different surnames. Those could easily be convergence, but if so why would you suppose that low resolution match to Dr. Dudley is not convergence?
Fourth, you have the problem that the Rice experts aren't entirely sure that your yDNA really represents the yDNA of immigrant John Rice. You seem to be a bit too distant from the other supposed descendant for comfort. It looks on the surface like there is an NPE somewhere between you and Joh Rice. That apparent problem is compounded because of your strong pattern of matches to Cochran men.
In addition to those four problems, there is also something a bit wonky about your match to Dr. Dudley. How did you find him? He doesn't come up in your list of matches at FTDNA. He doesn't appear to be a member of the Sutton project. So, it seems his results are either private or he didn't test at FTDNA.
There's also a problem if Dr. Dudley has tested 37 markers (as you imply). You'e tested 37 markets, so if there is a genuine match between you it should be much, much higher than 23/25. Are you leaving out the loss of the match at a higher resolution? Or has Dr. Dudley not yet tested 37 markers?
