Genalogy

I mentioned before that I've alwasy been proud of my Irish background. The trouble is, that besides my father, my aunt and my immediate family, we don't really know where the rest of them are. That's why I'm also working to see if I can find them. I've got a few leads, but I'm still a novice, both in tool and patience, but it's important to me to find them. We came from somewhere afterall. And are there more decendants here in the U.S.?
