Something else about this new group we found
Posted: Sat Sep 19, 2009 10:32 am
First of all, to explain our mixed references, the family line Donald and Roberta are discussing is the same group we have mentioned in various places as a line where we needed to have several people test 67 markers before it became obvious that it was distinct. I consider it a major discovery.
The reason we sometimes also refer to it as the Parker/Livingston group is that we have a Parker family in it. This Parker family already had stories of a possible Livingston connection, so this is one of those "exceptions that proves rules".
So having already mentioned the value of 67 marker upgrades for this group, there is something NEW we have discovered, which is that this group is negative for the SNP mutation named L21, although it is positive for P312. This is unusual enough to now make SNP testing interesting for many of our R1b participating families. For many others, the SNP status is ALREADY clear, but for those where the status is unclear, it would be very interesting to check whether you match Roberta and Donald's "Parker/Livingston" group.
Please feel free to contact me or post questions here about this.

Andrew
