Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal.

Eamon is one of the traditional Irish names that has not yet emigrated to the US. This Irish name pronounced ay-mon was popularized by early president of the independent republic Eamon de Valera (birth name George), who was born in the United States to an Irish mother and a Cuban father. Eamon definitely has possibilities as a successor to the epidemically popular Aidan/Aiden.

This appealing name has a good chance of catching on due to the popularity of Ewan McGregor, and the trend towards Gaelic names in general. Pronunciation is YOO-un.

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue.
