With its sharp, succinct sounds and cool, laidback style, Eli is a popular choice among parents today. Compact and punchy, it is a Biblical name with plenty of charm.

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.

Just as Seamus/Seumus is Irish for James, Hamish is the Scottish form — one that's not often used here, but still redolent of Olde Scotland.

Pronunciation is two syllables instead of one, like Colin with an 'm' at the end. Colm is related to Columba, Colom, Colum, Callum, and Malcolm.
