This update shows a new branch in Isles-C, represented by a single Big Y (shown in red).
Isles-C is a distinctive group which has a MRCA who lived approximately 2100 years ago. Isles-C is called I-Y5450, I-Y5455 etc. It's especially typical of central-western Ireland, as is Isles-D2 (I-Y4665).
Originally Ken Nordvedt named two clusters within Isles-C: Isles-C2 which has distinctive marker values especially DYS392=12, and Isles-C2 which contained everyone else. Over time we have identified several other branches as shown on this tree, but Isles-C2 (I-Y5451) remains the largest group.
