John,
As you know, I am null at 425, which is a rarity for R1b. Two other members of the Byrne project have 425=11. All the rest are 12.
According to an article that Phillip Goff and Whit Athey published in the JOGG several years ago, 98.1% of R1b have a 12 value for that marker, 1.3% have 13, 0.2% have 11, and 0.4% are null.
Checking your M222 project, I see that I am the only null 425, and one of my 11s (39360) is your project's only 11. I have sent you a request for the other 11 (117643) to join.
Recently I requested advanced 425 marker tests for my two third cousins, and they also are null. I also tested a Burns who lives in Sligo with whom I seem to have a common ancestor perhaps seven or eight generations ago, and he is null. This null must be a "private" indicator.
What puzzles me are not all these nulls, but the two 11s that are even more rare. We Burns nulls are fairly close to the two 11s in the other marker values. Null 425 is a recLOH, as I understand it, but are the 11s also the result of a recLOH, or half a one or something?
I am beyond my depth here and suppose I should query Thomas Krahn.
