Does anyone know the YDNA haplogroup of the Martin males of County Galway, descendants of Oliver Martin? I'm R1a1a, and my BigY-700 test shows that my YDNA line descends from the Martins. My family clade is R-YP658, and I have two matches in the Netherlands. But all the branches that spun off the family clade are either English or Irish. Two extensive Martin family genealogy books suggest Oliver Martin's Irish descendants may be been our immigrant to the American colonies. This is who were are trying to identify.
