If OP is this T-Y223124 bakool sample, he shares a common ancestor with the Dir-Isaaq subclade, T-BY181210, at T-L208 (8500 years ago). The bakool RX guy shares a subclade with Beni-Amers ( Beja and Habesha mixed people) in western Eritrea and eastern Sudan suggesting it's an old Cushite lineage. Proto-Somalis had more lineages than just E-Y18629 and T-BY181210.Why do you get T? Do you have any theory?
It's so odd to be getting T, especially the branch which is common among Dir.
I think you are of the Reer Majjuun subclan of Madaluug Dir who were assimilated by RX
