It depends on what you are looking for. If it is connected to a surname, then the Y-chrmosome would work in the paternal line to tell you whether there is any degree of common ancestry among people of that surname as compared with people in Ireland of any surname. The mtDNA test would not work because it is only inherited through the female line. However, if you are trying to find out where your mother's maternal ancestors originated, then the mtDNA test would work. I contacted a guy in New Zealand who found that his mother's Irish maternal line went back to the Ukraine in Eastern Europe, thus corroborating the view that Indo-European settlers whether Celt or Viking provided her maternal lineage.
