My father was M223+ (Y-search- HGJ8R). I haven't upgraded him to more testing because he is deceased and I am saving the sample. He has no close matches at 37. However, my brother or uncle could test if necessary.
Thanks for all of the comments!

The two new snps which separate M284+ into the young Scot clade and older
English clade were found from 23andMe tests rather than WTY.

I think we only had two folks from I2b1 M223+ do WTY.  If more from M223+
wished to do the WTY some thought should go into which kind of haplotypes
have the best chance of finding something.  They will be measuring the same
nucelotide sites as previous tests, so we'd want them to be exploring as
much virgin tree branch segments as possible.
