This is some of what I gleaned from Ancestry for you so it may pay if you are able to have a look. Obviously it is not certain that this has all been verified. My Byrnes are from the Glenmalure valley, Baravore Townland to be exact. There is a dim possibility your Byrnes and our Byrnes maybe distantly connected. All the best with it all. Bridget.
