Also, I really thought there would be a lot more SRY2627 at 23andMe, but that doesn't seem to be the case.

I looked at the FtDNA SNP map for SRY2627 and was surprised to see how many were based in Southeast England, along with the SW Scotland area. Many Atlantic French coast.
The iberianroots site show 145 SRY2627's and has a nice heat map which I am sure you have seen but others may not have.
