Hello All,
In our surname group, I've been focusing on seven people who have TMRCA estimated links between c1150 at around 99% in varying degrees to c1500's at around 90-95%.
Of these, all have DYS 391 = 11, whereas one has DYS 391 = 10.
Is there anything available which would determine the likelier oldest lineage?

Many thanks,
Bob
