The name Eamon is a boy's name of Irish origin meaning "wealthy protector". Eamon and is often added to lists like Irish Baby Names for Boys and discussed in our forums with posts like "A brother or sister for little Jack or Olivia".
From the experts:
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.
Though it may be an older generation name in Ireland, it would sound fresh elsewhere.
The original spelling of the name is Eamonn.
