When you look at our haplotrees, it's hard to tell which branches are most common. That's especially true because the I-P37 project makes a big effort to organize Big Ys for rarer branches.

If you look at our I-L160 tree, many of the general and specific branches are not very common. But we have learned that the I-A19395 branch is fairly common in northern Europe: Britain, Ireland, Germany, Poland, even one family from Finland. And maybe some Spanish families belong to I-A19395.

This update shows a third Big Y for I-A19395. All three Big Ys are for Irish/British men, but there is also one German/Polish man who received A19395+ results from an individual test at YSeq. And we can predict A19395+ results for many other men:

Most I-M26 men have the marker value DYS450=8 (part of the Y67 test). I-A19395 can be identified by DYS450=9. This DYS450=9 is also found in the related I-L1299 branch which is much less common. And DYS450=9 is also found in the distantly related I-F1295* branch. These other branches can be easily distinguished by other STR marker patterns.

I-A19395 has a MRCA who lived approximately 5000 years ago, and there isn't a strong STR marker pattern for I-A19395, except for the DYS450 value. So we weren't able to identify this branch before these Big Y results.
