This tree shows a new branch called I-BY65456, it's one of 22 known immediate subbranches of I-Y4252. This branch is based on two Big Y results, one for a man with ancestry from the 1800s from Shropshire, England, and another man with ancestry from the 1800s from Pomerania which is now part of Poland (they were German speakers). The second man has STR matches with some men from a German speaking family from slightly further east in Poland, they probably also belong to I-BY65456.
