Eoghan

Spuriously anglicized as Eugene and Owen. One of the most common names in early Ireland, borne by dozens of kings, warriors, and saints, of whom the most cited are probably Eógan(1), the son of Niall Noígiallach[of the Nine Hostages], and Eógan Mór of the Eóganacht dynasty in Munster.

Gender: Masculine
Usage: Irish Scottish
Pronounced: O-in, YO-in  

Possibly means "born from the yew tree" in Old Celtic. It is sometimes used as a Gaelic form of EUGENE.
