Please excuse me while I crow a bit. What a great day this is. Broke through my family brick wall. I just got my autosomal DNA test results. FOUND my half-brother. He had his YDNA test results. It turned out the haplogroup we are associated with goes way back to Erainn, or Ireland. I am just examining the tip of the iceberg on this. Can't believe it. DNA is the greatest thing ever. :)
