The story of Oisín

Oisín means “little deer”, from os (deer) and the small ending -ín. In the Fenian Cycle of Irish legend he is the son of Fionn mac Cumhaill and the great poet of the Fianna.

In the best-known story Niamh of the Golden Hair carries him across the sea to Tír na nÓg, the land of youth. After what feels like three years he asks to visit home, and finds that three hundred years have passed. He falls from his horse, touches the ground of Ireland and becomes an old man at once.

The name has been given in Ireland throughout the CSO records, and reached number 5 in 2022.
