Y2630 (Ashkenazi Levite clade) downstream from Y2619, upstream from YP264
YP450 downstream from Z2123, sibling to Y2632 and Y47 and Y937 and Y934 (Y934 not yet available, although its lone subclade Y874 is)

I am hoping that most of the Z2123 in Europe will be YP450+ . We have gotten a lot of negative results from the other Z2123 subclades (Y47 etc.).
