Was looking through the R1b charts and can see the diagrams for R1b still doesn't include CTS4528/DF100 as the new
3rd clade under L11 (P311). The date on the current chart shows it as being from July 2013.

In Oct 2014 ISOGG at last listed CTS4528/DF100 parallel to P312 & U106. We have been waiting years to get recognized
and are very pleased it has now happened. We do understand we are a rare line.

Who is the best person to contact about having the R1b charts & write ups upgraded ? - we are willing to help
where we can.
