Traditional Irish boys' names

Brian Boru, first high king of Ireland.
Brian Boru, High King of Ireland
Irish boys' names are largely drawn from tales of great warriors in Celtic Mythology or from early Ireland's regional kings. This isn't always immediately obvious because they've been adapted and changed spellings many times. But Brian is one of only very few Old Irish names that remains instantly recognisable.

Brian Boru is, by popular demand, history's greatest High King of Ireland who, as any Irish schoolboy will tell you, died at the Battle of Clontarf on Good Friday, 1014.

Such was his reputation that his name became extremely popular and was chosen with great pride for new-born sons through the centuries.

Even as a surname, when it it usually appears as O'Brien, it remains associated with the great warrior king. The name itself probably originated from the Celtic form Brigonos, from which the Irish name Bregon directly evolved, and changed first to Brion with two syllables and from then to Brian.

While Brian might be the greatest of all warrior names, there are others to choose from, as the list below shows.

The selection below is mine and by no means comprehensive. It includes some well-known Irish boys names as well as some that, though rarely encountered in recent times, may yet make a comeback if the current trend to seek out the unusual continues among new parents.
