Irish Genealogy

Once I learned that I was not from Puerto Rico, digging into the new family I learned that there were more family secrets to be uncovered. I took a Y-DNA test and found out that my roots clearly land up in Ireland. Even more than that was a story floating around about my great grandfather. Seems that he was adopted himself. It all adds up and DNA cousin matches seem to confirm what DNA told me, I am a LEAHY from County Kerry in Ireland. Now I just have to connect the dots. Below are some of the many resources I found helpful. I hope they are useful to you as you search out your Irish roots.
