Aodhan
(A-din) - Gaelic for "the fire within", I like that meaning a lot, and i think the name is really cute :)
Aodhan is traditonally a male name. It is the diminutive form of Aodh, which was the name of a Celtic fire god. His name means "fire." In Scottish Gaelic, Aodhan is pronounced more like /EU on/ or /EU ghon/. It is often anglicized Aidan.
