Ireland is a beautiful island filled with warm people and a rich culture. They also have a lot of beautiful and uncommon Irish baby names. Well, definitely uncommon if you don’t live in Ireland. These are not your typical American baby names. If you’re looking for something almost guaranteed to sound like a poem, an Irish baby name is the way to go. Irish Culture has had a significant influence on other cultures, especially in the fields of literature. Maybe that is why all the names are so lyrical sounding. Alongside mainstream Western Culture, a strong indigenous culture exists. This is most evident in the Gaelic games, Irish music and Irish language. Ireland’s culture shares many features with Great Britain, including the English Language, and favorite sports such as football, rugby, horse raising and golf. Yet, the people and the names of Ireland seem to be in a league of their own.

We all think of Patrick, Aidan, Liam, Mary Catherine, Molly. and Cathleen when we think of traditional Irish baby names. Maybe it’s movies, music or folklore but being American these names come to mind first when we think of Irish names. If you are of Irish heritage or you just love all things Irish, why not go with a baby name that is maybe not so common in your part of the world but easily identifiable as Irish in Ireland and unique.
