"My line matches with the O'Byrne Northeast Modal at DYS=481. It also matches with Maguires and McCown. My line does not match with the Leinster line of the O'Byrnes and is quite different form other Wexford Kehoes. As of 11/7/11 I'm the only DF23+, M222- known to exist." I am sure Miles understands this, but for the benefit of others, when we talk of Northwest Irish Burns/Byrne (M222), Leinster Burns/Byrne (L159.2), Northeast Burns/Byrne (L513), and a number of other "lineages" we are into the orange/apple bin. These are completely unrelated groups who coincidentally wound up with the same or similar surnames. The northeast Byrne group he mentioned is associated with McGuires of the Airghialla-2 modal.
