For reasons of space, we have created a new tree specific to I-Y4252.
I-Y4252 contains most of the I-L233 "Western" haplogroup. I-L233 had a MRCA who lived 2000 years ago according to YFull's latest calculation.
At this point, all known L233+ Y4252- men have British paternal origin, while the L233+ Y4252+ group contains men from Great Britain and Ireland, and from Continental Europe and Scandinavia. But maybe this simply reflects the much higher percentage of British origin men who have done Y-DNA tests (L233+ Y4252- is uncommon even in Britain).
This update shows a new branch called I-BY210124, it's found in SE Europe (Croatia and Albania). It's part of the larger I-A10033 branch which is maybe the most common branch of I-L233, and which is nearly always found in Continental Europe and Scandinavia (only 2 British families are known).
This update shows a new level called I-FT94277, it's the parent of the previously known I-A15050 branch.
This tree also shows a new sample in the I-BY160207 "Western-Isles" branch, this branch has exclusively British origin according to current knowledge.
