I just found a list of Gaelic names I wrote down from a Gaelic baby name book when I was pregnant with DD. I didn't write down the pronunciation, unfortunately, but I did write down the meanings. Like someone else posted, you should check the meanings of the Irish names. We found that many of the names for girls meant something negative. Some of these may be Welsh, but I think most are Irish.
